Part 2: the attached video, about 13 minutes, shows a ductile tearing instability fracture analysis to determine the critical crack size.  The example uses 3D crack meshes and elastic-plastic Abaqus/Standard analysis to compute the crack front J-integral values needed in the ductile tearing assessment. Refer to part 1 for information about the model and crack meshing. 

The example uses a nozzle in a reactor pressure vessel, and is based on a paper presented at the Science in the Age of Experience
