A trebly nonlinear computation: contact, behaviour and large deformations
3 May 2010
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.
