v6.03.147 SSNP147 — Modeling crack initiation with the ENDO_HETEROGENE model

Summary:

This test represents the initiation of a crack in a plate made of a heterogeneous material. This plate is subjected to a loading in the form of an imposed displacement ramp. Priming is modelled by law ENDO_HETEROGENE using regularized constraints. The objective of this test is to validate the D_ PLAN_GRAD_SIGM modeling and the ENDO_HETEROGENE law. This is a two-dimensional non-regression test case carried out on a rectangular and then triangular mesh.
