HOMARD : Non linear mechanical calculation for flaw propagation

French version

Red ball Description

The piece represents the quarter of a disk with a hole. The two vertical and horizontal axis modelizes symmetry. A radial pressure stress is applied. The propagation of a flaw is studied. At the beginning of the simulation, the flaw is located along the horizontal edge and is opened from the outside. Then, boundary elements are relaxed. The extreme point of the flaw goes to the inlet.
The initial global mesh is :

Along adaptations, the refined zone follows the evolution of the flaw. It is localized where more accuracy is needed for the calculation.
