v5.06.105 SDNS105 — Simulation of a dynamic pull test with cohesive elements

Summary:

The objective of this test is to validate elements with a cohesive zone of type CZM_EXP_REG in non-linear dynamics. A test to remove a square plate joined to a cohesive surface is simulated, taking into account thermal effects. This plate is subjected to a tensile force. The joint is heated beforehand and obeys a brittle fracture law RUPT_FRAG_F0 characteristic of elements CZM_*.
