3. Modeling A

3.1. Characteristics of modeling

3D modeling

Item MECA_HEXA8

3.2. Characteristics of the mesh

Number of knots: 8

Number of meshes and type: 1 HEXA8

Tested sizes and results

The deformations, the stresses and the damage value are compared at 3 different time steps (at the end of stage 1, during the growth phase of the damage and at the end of the loading).
