A trebly nonlinear computation: contact, behaviour and large deformations

by N. Tardieu, EDF R&D / AMA

This is a computation which models the crushing of a square-based shape in 0.1 second. The shape is composed of an elastoplastic steel with linear isotropic hardening.

The computation was realized in implicit nonlinear dynamics with the operator DYNA_NON_LINE and takes into account:

Inertia effect;
Plasticity;
Large deformations;
Contact (between the shape and its rigid base) and auto-contact.
