Abaqus failure tutorial #1: Stress Intensity Factor for 2D shell plate with longitudinal Crack.

[@CompanyofHeroes999]

Hello there. I have one question. How to check mesh convergence in crack analysis problems? Do I seek for K estimates to converge with finer mesh or something else?

Hi sir
How can I find SIF with change in crack length ?

[@GhandourYousef]

Hello! Once you have your stress intensity factors, how can you have the fracture criterion?
