Hello all,

I have a problem with the crack growth simulation using the SMART method in APDL. The model is very simple: a half plate (due to symmetry) with a central crack. One end is fixed and uniform tensile stress is applied to the other surface. The problem is that, even if I have refined the mesh near the crack tip, the SMART remeshing algorithm does not produce new crack surface with a good quality mesh and the propagation is stopped. The mesh is shown in the following picture:

If it is a 3D model, you can use SMART. If it is a 2D model, you need to use XFEM. Crack growth analysis in MAPDL is explained in the MAPDL Fracture Analysis Guide.nnn
