16. N modeling#
16.1. Characteristics of modeling#
Modeling: 3D.
Type VMIS_ISOT_TRAC elasto-plastic behavior law whose traction law is identical to that of B modeling.
The thermal deformation field from the thermomechanical calculation is extracted in order to be used as a control variable EPSA (command AFFE_MATERIAU) to represent a state of initial deformations of the structure.
16.2. Characteristics of the mesh#
The mesh is identical to that of modeling I.
16.3. Tested sizes and results#
Only the point in the middle of the crack front shown is tested.
