23. U modeling#
Validation of the implementation of law CZM_LIN_MIX in formulation X- FEM. We are testing the opening mode. This modeling is identical to modeling \(T\), but in plane deformations (D_ PLAN) instead of plane stresses (C_ PLAN).
23.1. Characteristics of modeling#
Strictly identical to modeling \(T\), except that the surface elements are of type D_ PLAN.
23.2. Characteristics of the mesh#
The square is discretized at the rate of \(4\) elements per side. Therefore:
Number of elements, type HEXA4: 16
Number of knots: 65.
23.3. Tested sizes and results#
The quantities tested are rigorously the same as in modeling \(T\), and are therefore obtained by the same calculations, according to the explanations in part 2.2.
