Popis:	We present here a finite element (FE) model for the efficient modelling of deep drawing and crashworthiness simulation of multi-material structures. The multi-layered continuum FE is formulated in large strains with normal and transverse shear stresses to model effectively the behaviour of a wide variety of structures from very thin, thick and volumetric 3D. The FE model is implemented in LS-DYNA code, in its implicit and explicit formulations, using a 2 × 2 integration in the shell plane for each layer, respectively and an arbitrary number of integration points in thickness direction. Numerical examples are presented and compared to experimental measurements to demonstrate the effectiveness of the present FE model. Nous presentons ici un modele FE pour la modelisation efficace de l’emboutissage et du crash de structures multi-materiaux. Le modele EF multicouches est formule en grandes deformations avec prise en compte de la deformation transverse et des deformations de cisaillement ce qui permet...
