    Accurate material properties of tissues are a key factor for the improvement of medical procedures and treatments. Experimental data are essential in order to formulate and validate a useful constitutive model for predicting the mechanical behavior of tissues in these procedures. This study develops a comprehensive experimental protocol at multiple length scale levels in order to obtain stress-strain curves for esophagus tissue. This paper compares two different models: a conventional, non-linear elastic model, and a microcontinuum model based on fiber rearrangement. Also, a detailed description of the experimental procedure is provided. While the focus was on esophageal tissues, the experimental procedure and microcontinuum are considered widely applicable to other samples of soft tissue.

    Objective: The objective of this study is to assess the response of postmortem human subjects (PMHS) to a large-volume side air bag in a fully instrumented and well-controlled side impact test condition. Methods: Three adult male PMHS were subjected to right-side pure lateral impacts. Each stationary seated subject was struck at 4.3 0.1m/s by a rigid wall installed on a 1700-kg rail-mounted sled. Each subject was held stationary by a system of tethers until immediately prior to being impacted by the moving wall. A large side air bag was mounted to the wall and deployed so that it was fully inflated at the time it contacted the subject's right side. The load wall consisted of an adjustable matrix of 15 individual plates, each supported by a 5-axis load cell that recorded the interaction between the subject and impacting wall. Two-dimensional (external) torso deformation was provided by a chest band that encircled the torso at the level of the sixth rib laterally. Triaxial acceleration was measured at the head, spine, and sacrum via 3 orthogonal accelerometers mounted to the same bone-mounted hardware that held the marker clusters used for kinematic analysis. Results: Peak pelvic load normal to the wall averaged 6.8 kN, which was over 5times that recorded for the shoulder (1.3 kN) and the thorax (1.2 kN). Lateral chest deflection ranged from 9 to 21mm. Two of the 3 subjects sustained 2 and 9 fractures, respectively. Conclusions: Two of the 3 PMHS sustained rib fractures despite low levels of thorax deflection. We attribute this finding to individual variability in subject injury tolerance. Other response parameters exhibited lower levels of variability and characterize PMHS response to a potentially beneficial side impact countermeasure.

    The goal of this study was to determine material properties for the anterior cortex and subcortical regions of human patellae and relate those properties to mineral density and fractal dimension of the bone. Ten human patellae were obtained from eight fresh frozen human cadavers and subjected to anteriorly-directed spherical indentation¿relaxation experiments using two different sized indenters to two different indentation depths. Response data were fit to a three-mode viscoelastic model obtained through elastic¿viscoelastic correspondence of the Hertzian contact relation for spherical indentation. A location-specific effective bone density measurement that more heavily weighted bone material close to the indentation site (by von Mises stress distribution) was determined from micro-computed tomography (38 µm resolution) data captured for each specimen. The same imagery data were used to compute location specific fractal dimension estimates for each indentation site. Individual and averaged patella material models verified the hypothesis that when the larger indenter and greater indentation depth is used to engage the surface and deeper (trabecular) bone, the bone exhibits a more compliant response than when only the surface (cortical) bone was engaged (instantaneous elastic modulus was 325 MPa vs. 207 MPa, p<0.05). Effective bone mineral density was shown to be a significant predictor of the elastic modulus for both small and large indentation types (p<0.05) despite relatively low correlations. Exponential regressions of fractal dimension on elastic modulus showed significant relationships with high correlation for both the small (R2=0.93) and large (R2=0.97) indentations.

    Esta tesis es una investigación sobre el comportamiento mecánico del esófago humano. Este trabajo se pensó para ser aplicado al tratamiento de la estenosis y otras afecciones esofágicas que, con frecuencia, requieren dilatación forzada, lo que supone altas presiones sobre la pared esofágica. Este estudio propone un modelo constitutivo para simular estas dilataciones forzadas. Este estudio incluye la caracterización experimental del comportamiento mecánico del esófago. Además, se han planteado algunas cuestiones teóricas y experimentales que han sido resueltas.Esta tesis resume el trabajo previo sobre tejido esofágico de otros investigadores. Además, se da una pequeña explicación sobre la teoría del medio microntinuo desarrollada en las últimas décadas y un breve resumen de la teoría general de modelos constitutivos hiperelásticos no-lineales (con grandes deformaciones). El estudio requirió experimentación de tejido para caracterizar el comportamiento in vitro. Los test incluyeron test de tracción y test de inflado. Se empleó rastreo óptico para un cálculo adecuado de la deformación. Los resultados de los test permitieron encontrar las propiedades mecánicas según dos modelos de esófago de la literatura. El análisis de los datos rebeló, algunas correlaciones significativas entre factores como el índice de masa corporal y algunas propiedades mecánicas. Los valores típicos de las propiedades fueron usados para algunas simulaciones numéricas basadas en los modelos propuestos. Además se han obtenido algunos resultados teóricos sobre la tensión residual y las predicciones de la mecánica estadística para un sistema de fibras de colágeno del tejido.El principal resultado es un modelo constitutivo de microestiramiento anisótropo no-lineal e hiperelástico para caracterizar el esófago. Este modelo es adecuado para la computación numérica.

    This dissertation is a research about the mechanical behavior of the human esophagus. This work is intended to be applied in the treatment of stenosis and other esophageal diseases that frequently require a procedure of forced dilation, that involves high pressures on the esophagus wall. This study proposes a constitutive model to simulate forced dilatations. This study includes the experimental characterization of the mechanical behavior of human esophagus. In addition, some theoretical questions and experimental issues were addressed and solved. This dissertation summarizes the previous work on esophageal tissues by other authors. Additionally, a short explanation about the microcontinuum theory developed in the last decades is given, as well as a summary of the general theory of nonlinear hyperelastic constitutive models (with large deformation). This study required extensive testing of esophageal tissue in order to characterize the in vitro mechanical behavior. The testing included mainly tensile tests and complementary inflation tests. Optical motion track analysis was used for accurate computation of the strains in the tissue. The results of the tests were used for adjusting the mechanical properties that characterize the mechanical behavior of esophagus in the proposed models of the literature. The statistical analysis of the data revealed, some significant correlations between anthropometric factors, such as the body mass index, and some mechanical properties were found in the analysis of the data. The typical values of the mechanical properties were used to perform some numerical finite element simulations based on the proposed models. In addition, a number of theoretical results were obtained concerning the residual stress and the predictions of statistical mechanics for a system of collagenous fibers inside a soft tissue. The main result is a constitutive non-linear microstretch anisotropic hyperelastic constitutive model with large deformations (and with residual stresses) to characterize the multi-layered tissue of human esophagus. This model is suitable for numerical simulation.

    Rear-impact collisions at low speed are the most frequent type of accident among all motor vehicle crashes. These collisions are also the subject of substantial investigation in the scientific literature neck injuries associated with them are commonly known as whiplash. The difficulty to identify an injury of this kind with an objective basis leads to litigation and high social costs. Costs in Europe have been estimated at between 5-10 billion euros each year, and this number increases annually. The aim of this paper is to establish clearly and rigorously the kinematic mechanism that the neck undergoes during a low-speed rear impact. The main criteria for injury accepted by the scientific community and used in the automotive industry will be analyzed. Finally, an analysis of the different aspects that could modify the nature of the collision will be conducted.

    An analysis of the possible causes of the collapse of an attraction (El Péndulo) located in the amusement park of Tibidabo (Barcelona) has been performed. This analysis corroborates some hypotheses asserted by Professional association of Industrial Engineers of Catalonia (COEIC) by numerical computations. The accident caused a fatality and additional injured people. This attraction was opened in August of 2006, that indeed, it lasted for 4 years. In the analysis carried out, it is analyzed in detail the most probable hypothesis that could have happened focusing the causes of the collapse on the preloaded screws provided to the lower base of el Péndulo and the presence of corrosion on the screws. Publicly known data have been used for an accurate reconstruction of the geometry of el Péndulo. This is used for kinematical and dynamical computations in detail. These suggest to discard some possible failure causes, and they point to corrosion and tightening torque as factors involved in the collapse.

    This research presents six simultaneous innovative occupant near side lateral impact protection concepts, including a dynamic door, a high-volume side airbag, a large external airbag that covers doors, sill and B-pillar of the struck vehicle and other concepts for increasing the distance between the occupant and the door panel (active armrest, inflatable door beam and moving seat). All systems are based on pre-crash detection of the impact and are activated as soon as 80 ms before the impact. This paper details the task of integrating these systems into a vehicle using finite element models, sled tests and full scale crash tests.

    The goal of this study was to evaluate the biofidelity of the Global Human Body Models Consortium (GHBMC) human body model under a side impact loading condition with an airbag, and analyze the effect of initial position of the model on the response. Shaw et al. conducted side impact sled tests using three Post mortem human surrogates (PMHS) with impact speeds of 4.3 ± 0.1 m/s, and used a rigid wall boundary condition with an airbag mounted to the sled. The correlation between the PMHS and the GHBMC was evaluated using the CORA rating method. The rating ranged from 0.27 to 0.69 along the body regions on a scale in which a rating of 1.0 indicated a perfect correlation between the PMHS and the GHBMC. The pelvis and thorax region showed good correlation with those of the PMHS while the spinal regions did not. In addition, the roll and yaw angle of the initial position of the PMHS had an effect on the response of subjects. The result of this research indicated two points, that the GHBMC model should be validated focusing on the internal biofidelity of the model, and that the yaw and roll angle should be carefully controlled during a side impact test.

    This study compares head impact dynamics between post-mortem human surrogates (PMHS) and the Polar-II pedestrian crash dummy in vehicle–pedestrian impacts with a small sedan and a large sports utility vehicle (SUV). A total of 15 (8 sedan and 7 SUV) full-scale vehicle pedestrian impact tests were performed at 40 km/h. For each vehicle, two (SUV) or three (sedan) PMHS tests and five dummy tests were performed, with three of the dummy tests in the same configuration to show repeatability, and the other two tests utilising slightly different configurations. Head linear and angular kinematics were captured from PMHS and dummy head instrumentation, and dummy upper neck load cell data were used to determine neck forces and calculate head impact forces. Differences in head impact locations, timing and kinematics between the dummy and PMHS were minimised when the dummy was positioned higher above the ground reference level to match the pelvis height of the PMHS. On average, the dummy recorded higher resultant impact forces (2930 N vs. 1862 N) in windshield impacts to the sedan than in hood impacts to the SUV, which resulted in higher 15-ms Head Injury Criteria (HIC15) values and higher peak and averaged angular accelerations. While there are differences in dummy injury risk metrics, both the dummy and PMHS data show that the difference in injury risk metrics predicted by the dummy can be explained by the variation in impact velocity between the sedan (14.1 ± 1.2 m/s) and the SUV (10.7 ± 2.3 m/s), the differences in injury risk predicted by the PMHS are not as clear due to confounding factors. The data and analyses presented in this study also show that neck forces during head impacts contribute a substantial and additive effect to the head impact accelerations (and thus HIC15 values) measured in the dummy, and that for the SUV, neck forces affect head accelerations more than impact forces. Despite analysing only lateral impacts with two vehicle geometries at 40 km/h, this study provides the only comparison of PMHS and dummy pedestrian head impact kinematics data available.

    A test series involving direct right-side impact of a moving wall on unsupported, unrestrained cadavers with no arms was undertaken to better understand human kinematics and injury mechanisms during side impact at realistic speeds. The tests conducted provided a unique opportunity for a detailed analysis of the kinematics resulting from side impact. Specifically, this study evaluated the 3-dimensional (3D) kinematics of 3 unrestrained male cadavers subjected to lateral impact by a multi-element load wall carried by a pneumatically propelled rail-mounted sled reproducing a conceptual side crash impact. Three translations and 3 rotations characterize the movement of a solid body in the space, the 6 degrees of freedom (6DoF) kinematics of 15 bone segments were obtained from the 3D marker motions and computed tomography (CT)-defined relationships between the maker array mounts and the bones. The moving wall initially made contact with the lateral aspect of the pelvis, which initiated lateral motion of the spinal segments beginning with the pelvis and moving sequentially up through the lumbar spine to the thorax. Analyzing the 6DoF motions kinematics of the ribs and sternum followed right shoulder contact with the wall. Overall thoracic motion was assessed by combining the thoracic bone segments as a single rigid body. The kinematic data presented in this research provides quantified subject responses and boundary condition interactions that are currently unavailable for lateral impact.

    This study aims to present all of the injuries sustained by 17 post-mortem human surrogates(PMHS)tested in vehicle-pedestrian impact experiments and explore the injuries, their sources, mechanisms and clinical relevance by comparing them to injuries sustained by 24 PMHS from previous literature and by the pedestrians that were entered into a recent in-depth database of vehicle pedestrian crashes. The 17 PMHS were tested in lateral impact by one of five late model production vehicles at 40 km/h in a controlled laboratory setting and all of their injuries were examined in detail. The Crash Injury Research and Engineering Network CIREN) program enrolled 67 US vehicle‐pedestrian crash cases between 2002 and 2007, and in-depth analysis of the pedestrians’injuries, injury mechanisms and sources was conducted by a team of biomechanical engineers, crash investigators and trauma physicians. The PMHS tests resulted in greater frequency and severity of spinal injuries, pelvic injuries and knee injuries than in the case studies, partially due to age and bone quality of the PMHS, and partially due to the effect of active musculature. Both the PMHS and the case studies showed that sustaining a knee or leg injury in one lower extremity protects against sustaining a concomitant leg or knee injury to the same lower extremity.
