The objective of this contribution is to investigate the influence of morphological and crystallographic textures on the formability limits of polycrystalline aggregates using the Crystal Plasticity Finite Element Method ... -

The impact of material models on the numerical simulation of springback is investigated. The study is focused on the strain-path sensitivity of two hardening models. While both models predict the Bauschinger effect, their ...

An elastic-plastic micromechanical behavior model written in the finite strains framework is presented. It is shown that the present model is able to reproduce the behavior for BCC materials during simple and complex loading ...

In this work, the formulation of the finite element “SHB8PS” is revisited in order to eliminate some persistent membrane locking or transverse shear locking. Let us recall that the “SHB8PS” is a continuum mechanics shell ...

This work aims to study the strain localization during the plastic deformation of sheets metals. This phenomenon is precursor for the fracture of drawing parts, so its prediction using advanced behavior models is an active ...

La modélisation du comportement des tôles lors de la mise en forme est nécessaire pour la compréhension et la prédiction de nombreux phénomènes (retour élastique, striction localisée, variation d’épaisseur et ondulations ...

This work consists to study the spring back in the deep drawing of flat sheets. A phenomenological elastoplastic model taking into account the strain path change was implemented in the ABAQUS software using an implicit ...
