5. C modeling#
5.1. Characteristics of modeling#
It is a nonlinear elasticity calculation under the hypothesis of small displacements, in axisymmetric mode. The crack is open in pure I mode. Only half of the structure is represented by symmetry.
5.2. Characteristics of the mesh#
The mesh is identical to that of modeling A.
5.3. Tested sizes and results#
The results obtained for three different integration rings are compared:
