v6.07.103 COMP003 — Test of behaviors specific to concrete. Simulation at a hardware point

Summary:

This test involves a simulation of a loading path in stresses or deformations at a material point, i.e. on a model such that the stress and deformation states are homogeneous at all times. It thus makes it possible to test a certain number of behavior models specific to concrete, in order to verify the robustness of their numerical integration, their insensitivity to a change of units, the correct consideration of the control variables on which the coefficients of the model depend, the invariance with respect to a global rotation applied to the problem.

Modeling A: this modeling makes it possible to validate model BETON_RAG in \(\mathrm{3D}\).

B modeling: this modeling makes it possible to validate model BETON_UMLV in \(\mathrm{3D}\).

C modeling: this modeling makes it possible to validate model BETON_BURGER in \(\mathrm{3D}\).

D modeling: this modeling makes it possible to validate model ENDO_LOCA_EXP in \(\mathrm{3D}\).
