    El mecanizado de metal es un proceso en el que una capa delgada de metal se retira por una herramienta en forma de cuña de un cuerpo grande . El corte es un complejo de fenómenos físicos en los que la fricción, bandas de cizalla adiabáticas , calentamiento excesivo , grandes deformaciones y de alta velocidad de las herramientas están presentes. La geometría de la herramienta , ángulo de ataque y la velocidad de corte juegan un papel importante en la morfología de la viruta , las fuerzas , el consumo de energía y desgaste de la herramienta de corte. El objetivo principal del trabajo es contribuir precisamente a resolver algunos de los problemas descritos anteriormente a través de la extensión del PFEM a los problemas termo-mecánicos en mecánica de sólidos que implican grandes deformaciones y rotaciones , múltiples contactos y generación de nuevas superficies, con el foco principal en la simulación numérica de procesos de corte de metal . El problema termomecánico, formulado en el marco de la mecánica de medios continuos , se integra usando un esquema isotérmico junto con esquemas implícitos , semi-explícito y Implex. La herramienta ha sido discretizado utilizando un elemento finito triangular de tres nodos estándar. La pieza se discretizado utilizando un elemento finito desplazamiento presión mixta para hacer frente a la condición de incompresibilidad impuesto por la plasticidad . El elemento finito mixto se ha estabilizado mediante la proyección polinómica Presión, aplicado inicialmente en la literatura para la ecuación de Stokes. El comportamiento de la herramienta se describe usando un modelo constitutivo hiperelástico Neo Hookean . El comportamiento de la pieza de trabajo se describe usando un modelo isotrópico , con elastoplasticidad j2 y con tres funciones diferentes que se utilizan para describir el endurecimiento por deformación , endurecimiento de la velocidad de deformación y el ablandamiento térmico de diferentes materiales bajo una amplia variedad de condiciones de corte . La fricción en la interfaz de la herramienta-viruta se modela utilizando la fricción ley Norton- Hoff . La transferencia de calor en la interfase herramienta-viruta incluye la transferencia de calor por conducci{on y por fricción. Para validar la formulación desplazamiento presión mixto propuesto, se presentan tres problemas de referencia (la membrana de la tensión normal de Cook, la prueba de impacto Taylor y una prueba de tracción termomecánica ). La división isotérmica - IMPLEX presentada en este trabajo ha sido validado mediante un ensayo de tracción termomecánica . Además , con el fin de explorar las posibilidades del modelo como una herramienta para ayudar en el análisis de los procesos de corte de metal, un conjunto de simulaciones se presentan en este trabajo, entre ellas : corte de una material con tensión de fluencia independiente de la tasa de deformación , cortando utilizando diferentes ángulos de ataque , corte con herramientas de corte deformables incluyendo la fricción y la transferencia de calor , la transición de la continua para la formación de viruta dentada aumento de la velocidad de corte . Además, nuestros resultados muestran que la selección adecuada del esquema global de integración de tiempo puede suponer un ahorro en el tiempo de cálculo hasta 9 veces. Por otra parte, este trabajo presenta un análisis de sensibilidad a las condiciones de corte mediante un diseño de experimentos (DOE) . El diseño de experimentos con el llevado a cabo PFEM ha sido comparada con la llevada a cabo con el DoE AdvantaEdge , deforme, Abaqus y experimentos.. Los resultados obtenidos con PFEM y otras simulaciones numéricas son muy similares, mientras que , en comparación de las simulaciones numéricas y experimentos muestran algunas diferencias en las variables de salida que dependen de los fenómenos de fricción. Los resultados sugieren que es necesario mejorar la modelización de la fricción en la interfaz de la herramienta-viruta.

    Experimental and numerical studies of powder flow during the die filling stage in powder metallurgy cold compaction processes are presented. An experimental setting consisting of a horizontal pneumatically activated shoe, a vertical die and high-speed video system has been designed. The experiments show the existence of three flow regimes: continuous, transitory and discrete, which are identified in terms of the particle size, the morphology and the speed of the shoe. In the continuous regime the powder flows in a progressive manner but in the discrete one some perturbations appear as a consequence of a shear band formation that forms discrete avalanches. A numerical model, based on a ratedependent constitutive model, via a flow formulation, and in the framework of the particle finite element method (PFEM) is also proposed. For the purpose of this study, the use of the PFEM assumes that the powder can be modelled as a continuous medium. The model, provided with the corresponding characterisation of the parameters, is able to capture the two fundamental phenomena observed during the filling process: (1) the irreversibility of most of the deformation experienced by the material and (2) the quick dissipation of the potential gravitatory energy of the granular system through the inter-particle friction processes, modelled by the plastic dissipation associated with the material model. Experimental and numerical results have been compared in order to study the viability of the proposed model.

    This paper deals with the question of how to efficiently integrate a constitutive model that describes the densification of powders and the potential formation of cracks in Powder Metallurgy (P/M) cold compaction processes. The analyzed model is a large strain, elastoplastic model of the Drucker–Prager/Cap type, refined to cover also the prediction of crack formation, and featuring non-conventional elements such as a density-dependent Von Mises yield surface; a parabolic plastic potential function for the Drucker–Prager envelope; and a softening law whose softening modulus is dependent on the level of densification. The employed integration procedure is a non-conventional hybrid or IMPLicit–EXplicit (IMPL-EX) scheme, whose essence is to solve explicitly for some variables and implicitly for others, with the peculiarity of the ‘explicit’ variables being but extrapolated values of the same quantities computed, at previous time steps, by means of a fully implicit scheme. The return-mapping equations stemming from this implicit scheme are solved using an unconditionally convergent, fractional step method-based iterative procedure. The performance of the IMPL-EX integration algorithm is critically assessed in two different situations: the densification of a cylindrical specimen, and the fracture process in a diametral compression test. Results obtained show conclusively that the proposed hybrid integration strategy offers an efficient solution to the trade-off between robustness and computational time requirements.

    The work focuses on the numerical resolution of the discontinuous material bifurcation problem as a relevant ingredient in computational material failure mechanics. The problem consists of finding the conditions for the strain localization onset in terms of the so-called bifurcation time, localization directions and localization modes. A numerical algorithm, based on the iterative resolution of a coupled eigenvalue problem in terms of the localization tensor, is proposed for such purpose. The algorithm is shown to be always convergent to the exact solution for the symmetric case (major and minor symmetries of the tangent constitutive operator). In the unsymmetric case (only minor symmetries), the solution is no longer exact, although it is shown that using the symmetric part of the localization tensor in the proposed algorithms provides enough accurate solutions for most of cases. Numerical examples illustrate the benefits of the proposed methodology in terms of accuracy and savings in the computational cost associated with the problem.

    The work presents the most relevant features of a numerical simulation setting based on the Particle Finite Element Method. The method is especially suitable for dynamic problems in computational solid mechanics where a fluid-like behavior is experienced by the solid i.e.: metal forming processes, powder compaction processes and granular flows, characterized by large strains and distortions, and those displaying new appearances and changes of existing solid boundaries, like in machining processes. The main elements of the method are: a) the updated Lagrange description of the motion, b) an automatic boundary recognition procedure (the alpha-shape method), c) appropriated constitutive models and integration algorithms and 4) a specific contact-domain based method to impose the contact constraints.

    This second part of the work describes the numerical aspects of the developed contact domain method for large deformation frictional contact problems. The theoretical basis of this contact method is detailed in the first part of this work. Starting from this, the present contribution focuses on describing important algorithmic details that go along with the finite element implementation for two-dimensional problems. Important aspects are the construction of the contact domain mesh, via a constraint Delaunay triangulation, the linearization of the discretized contact contributions and some important technical aspects about the extrapolation procedure used for the predictive active set strategy. Finally a set of numerical examples is presented to demonstrate the performance of the developed contact strategy. Demanding static and dynamic contact problems in the context of large deformations, including frictional effects as well as self contact, show the wide applicability and the robustness of the proposed method.

    Powder metallurgy (P/M) is an important technique of manufacturing metal parts from metal in powdered form. Traditionally, P/M processes and products have been designed and developed on the basis of practical rules and trial-and-error experience. However, this trend is progressively changing. In recent years, the growing efficiencies of computers, together with the recognition of numerical simulation techniques, and more specifically, the finite element method , as powerful alternatives to these costly trial-and-error procedures, have fueled the interest of the P/M industry in this modeling technology. Research efforts have been devoted mainly to the analysis of the pressing stage and, as a result, considerable progress has been made in the field of density predictions. However, the numerical simulation of the ejection stage, and in particular, the study of the formation of cracks caused by elastic expansion and/or interaction with the tool set during this phase, has received less attention, notwithstanding its extreme relevance in the quality of the final product. The primary objective of this work is precisely to fill this gap by developing a constitutive model that attempts to describe the mechanical behavior of the powder during both pressing and ejection phases, with special emphasis on the representation of the cracking phenomenon. The constitutive relationships are derived within the general framework of rate-independent, isotropic, finite strain elastoplasticity. The yield function is defined in stress space by three surfaces intersecting nonsmoothly, namely, an elliptical cap and two classical Von Mises and Drucker-Prager yield surfaces. The distinct irreversible processes occurring at the microscopic level are macroscopically described in terms of two internal variables: an internal hardening variable, associated with accumulated compressive (plastic) strains, and an internal softening variable, linked with accumulated (plastic) shear strains. The innovative part of our modeling approach is connected mainly with the characterization of the latter phenomenological aspect: strain softening. Incorporation of a softening law permits the representation of macroscopic cracks as high gradients of inelastic strains (strain localization). Motivated by both numerical and physical reasons, a parabolic plastic potential function is introduced to describe the plastic flow on the linear Drucker-Prager failure surface. A thermodynamically consistent calibration procedure is employed to relate material parameters involved in the softening law to fracture energy values obtained experimentally on Distaloy AE specimens. The discussion of the algorithmic implementation of the model is confined exclusively to the time integration of the constitutive equations. Motivated by computational robustness considerations, a non-conventional integration scheme that combines advantageous features of both implicit and explicit method is employed. The basic ideas and assumptions underlying this method are presented, and the stress update and the closed-form expression of the algorithmic tangent moduli stemming from this method are derived. This integration scheme involves, in turn, the solution at each time increment of the system of equations stemming from a classical, implicit backward-Euler difference scheme. An iterative procedure based on the decoupling of the evolution equations for the plastic strains and the internal variables is proposed for solving these return-mapping equations. It is proved that this apparently novel method converges unconditionally to the solution regardless of the value of the material properties. To validate the proposed model, a comparison between experimental results of diametral compression tests and finite element predictions is carried out. The validation is completed with the study of the formation of cracks due to elastic expansion during ejection of an overdensified thin cylindrical part. Both simulations demonstrate the ability of the model to detect evidence of macroscopic cracks, clarify and provide reasons for the formation of such cracks, and evaluate qualitatively the influence of variations in the input variables on their propagation. Besides, in order to explore the possibilities of the numerical model as a tool for assisting in the design and analysis of P/M uniaxial die compaction (including ejection) processes, a detailed case study of the compaction of an axially symmetric multilevel part in an advanced CNC press machine is performed. Special importance is given in this study to the accurate modeling of the geometry of the tool set and the external actions acting on it (punch platen motions). Finally, the potential areas for future research are identified.

    A numerical model, based on a rate-dependent constitutive model, via a flow formulation, and in the framework of the particle finite element method (PFEM) is proposed. It is settled on the assumption that the powder can be modelled as a continuous medium. The model, provided with the corresponding characterization of the parameters, is able to capture the two fundamental phenomena observed during the granular material flow: 1) the irreversibility of most of the deformation experienced by the material and 2) the energy dissipation of the granular system through the inter-particle friction processes, modelled by the plastic dissipation associated with the material model. Experimental and numerical results have been compared in order to study the viability of the proposed model.

    In the first part of this work, the theoretical basis of a frictional contact domain method for two-dimensional large deformation problems is presented. Most of the existing contact formulations impose the contact constraints on the boundary of one of the contacting bodies, which necessitates the projection of certain quantities from one contacting surface onto the other. In this work, the contact constraints are formulated on a so-called contact domain, which has the same dimension as the contacting bodies. This contact domain can be interpreted as a fictive intermediate region connecting the potential contact surfaces of the deformable bodies. The introduced contact domain is subdivided into a non-overlapping set of patches and is endowed with a displacement field, interpolated from the displacements at the contact surfaces. This leads to a contact formulation that is based on dimensionless, strain-like measures for the normal and tangential gaps and that exactly passes the contact patch test. In addition, the contact constraints are enforced using a stabilized Lagrange multiplier formulation based on an interior penalty method (Nitsche method). This allows the condensation of the introduced Lagrange multipliers and leads to a purely displacement driven problem. An active set strategy, based on the concept of effective gaps as entities suitable for smooth extrapolation, is used for determining the active normal stick and slip patches of the contact domain.
