**v6.03.114** FORMA03 - Practical work from the "Advanced use" training course: limit load of a perforated plate
====

**Summary:**

This test :math:`\mathrm{2D}` in quasistatic plane stresses makes it possible to illustrate questions relating to elastoplastic modeling on a simple case; it highlights the effects of structure, stress concentration, and limit load.

It is a homogeneous rectangular plate, with holes in its center, made of an elastoplastic material with isotropic work hardening, whose initial state is unstressed, which is subjected to traction at its ends. We are interested in the elastoplastic solution in charge.

The objective of the test is to show modeling possibilities, the use of the STAT_NON_LINE command, and post-processing with the Salome-Meca platform.

Modeling A corresponds to the force-imposed elasticity calculation. It illustrates the use of the STAT_NON_LINE command in a simplified configuration (purely elastic linear calculation). It also serves as a reference for other models.

Modeling B corresponds to the force-imposed calculation, reference with behavior VMIS_ISOT_TRAC, and illustrates the use of the various parameters of the STAT_NON_LINE command, as well as the counting commands.

Modeling C explains the procedure for carrying out the calculation up to the limit load, using the control of the load by a displacement.

D modeling is the same as C modeling except that it uses follower loading.
