Crack simulation in Abaqus: J-integral, designing mesh around crack

In this video simulation of crack onset in the Abaqus software using J-integral is explained. In this video you can find out: How to Create a crack in Abaqus? How to partition the part to control mesh around the crack? How to create appropriate mesh singularity? Which kind of mesh is appropriate around a crack? How to define crack tip and seam? How to set elements singularity for linear elastic fracture mechanics? How to request J-integral values? How to plot or extract J-integral values? How to predict onset of crack extension?
