6. D modeling#
6.1. Characteristics of modeling#
It is a nonlinear elasticity calculation under the hypothesis of small displacements, in plane deformations. The crack is opened in mixed mode. The entire structure is shown. A non-uniform stationary temperature is applied.
6.2. Characteristics of the mesh#
The mesh is identical to that of modeling B.
6.3. Tested sizes and results#
The results obtained for three different integration rings are compared:
