Large deformation finite element analysis with inelastic constitutive models including damage

摘要

In this paper, the kinematic quantities needed for the description of finite deformations with inelastic constitutive models are summarized and the formulation of an inelastic mateial model for large deformations is given. Here, the Bodner-Partom model is used and extended to include damage effects based on Gurson's model. An approximation of the constitutive model is given which takes into account the volumetric constraint and which is suitable for the incremental numerical scheme.
