v6.01.115 SSNA115 — Pulling a rigid frame with cohesive elements

Summary:

The object of this test case is the numerical study of the removal of a rigid frame embedded in a hollow cylinder. Decohesion is described with two cohesive models. :

B modeling: based on joint elements with the cohesive law CZM_LIN_REG (see documentation [R7.02.11]) using the AXIS_JOINT modeling.

C modelling: based on interface elements with the cohesive law CZM_TAC_MIX (see documentation [R7.02.11]) using the AXIS_INTERFACE_S modeling.

To validate the results we will rely on the analytical solution developed in [bib3]. Interested readers can also refer to it for a more in-depth study of this test case.
