Simulation ellipsoid crack in the pressure vessel under variable pressure with subroutine

In this video you can see step by step tutorial of ellipsoid crack in the pressure vessel under internal and external pressure in ABAQUS sofware.The internal pressure is fixed but the external pressure is variable with time and location. For calculation the external pressure we used DLOAD subroutine as function of time and location. The goal of this tutorial is achieving J Integral for crack tip. On the other hand for better performance of element in the crack analysis we use Singular element on the crack tip. In the bellow figures you can see some result of this simulation
