Abstract
This paper highlights an explicit integration scheme for hyperelastic-based finite strains elasto-plastic models. One step update equations are obtained from the large deformation multiplicative elasto-plastic theory, where an exponential variation of the plastic deformation gradient is assumed. The material tangent matrix has the same formal structure as the usual small strains elasto-plastic tangent matrix. The basic algorithm to perform the stress integration, including an adaptive substeppin...
