v6.04.400 SSNV400 — Verification of the law of behavior BETON_RAG: damaging mechanics

Summary:

These tests validate the BETON_RAG law of behavior on a cube subjected to tension or compression, with a radial loading path. The response of the model is compared to solutions obtained by analytically solving the equations that govern the behavior [R7.01.26].

Four models are proposed:

• Modeling a: tensile test under imposed deformation, on a cube free from deforming in the direction perpendicular to the load.

• Modeling b: compression test under imposed deformation, on a cube that is free to deform in the direction perpendicular to the load.

• Modelling c: tensile test under imposed deformation, on a confined cube (blocked transverse deformations).

• Modelling: compression test under deformation imposed on a confined cube (blocked transverse deformations).
