**v3.04.154** SSLV154 — Circular crack in mixed mode
========================================================

**Summary:**

The purpose of this test is to validate the calculation of 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.

This test contains 2 models:


* Modeling A: the crack is meshed (FEM) with a radiant mesh at the bottom of the crack;


* B modeling: the crack is not meshed, it is represented by level-sets (X- FEM)


* C modeling: the crack is meshed (FEM) for incompressible elements (_ INCO_UPG);


* D modeling: the crack is meshed (FEM) with free mesh from Zcracks

For each model, SIFs are evaluated by commands POST_K1_K2_K3 and CALC_G.

Numerical values are compared to analytical values.
