1. But#

Calculate the mechanical evolution of a material point, in non-linear quasistatics.

All of the behaviors that are available in STAT_NON_LINE [U4.51.11] are also available here.

The aim of this macro command is to simplify the data as much as possible: all you have to do is provide:

  1. Behaviour and material;

  2. The functions defining the evolution of the selected stress or deformation components;

  3. Discretization in time.

In particular, this makes it possible to calculate the evolution of the stress tensor in the case of imposed deformations, or the opposite (common cases in identifying material parameters)

Produces a table-type data structure containing, as a function of time, the evolution of all the components of the stress and strain tensors, as well as the internal variables.
