v6.03.164 SSNP164 — 2D and 3D joints for law JOINT_MECA_ENDO

Summary:

The purpose of this test is to validate hydro-mechanical joint elements for the law of behavior of dams JOINT_MECA_ENDO.

We test both the pure mechanical models PLAN_JOINT in \(\mathrm{2D}\) (mesh QUAD4, QUAD8) and 3D_ JOINT in \(\mathrm{3D}\) (mesh HEXA8, HEXA20 or PENTA6, PENTA15) in the presence of imposed pressure. Then, for the same quadratic elements, the coupled hydro-mechanical models PLAN_JOINT_HYME and C3D_ JOINT_HYME are also tested, with the underpressure profile obtained in the calculation.

The elements on which these models are based are the standard cohesive joint elements.
