v6.04.159 FORMA08 - Practical work from the « Fracture mechanics » training course: circular crack in mixed mode

Summary:

The purpose of this test is to validate the calculation of the energy restoration rate and stress intensity factors (SIFs) along the bottom of a 3D crack in mixed mode, in the context of linear elasticity.

This test involves a cube with a flat central circular crack, subjected to a force inclined with respect to the plane of the crack.

For each model, the SIFs are evaluated by the CALC_G command option G and K.

Numerical values are compared to analytical values.
