Workshop: Simulation Ellipsoid Crack In The Pressure Vessel Under Variable Pressure With Subroutine

In this tutorial, you will see a step-by-step simulation of an ellipsoid crack in a pressure vessel using Abaqus software. The vessel is subjected to both internal and external pressure. The internal pressure is constant, while the external pressure varies with time and location.

To calculate the external pressure, we use the DLOAD subroutine as a function of time and position. The main objective of this tutorial is to obtain the J-Integral at the crack tip. For improved accuracy in crack analysis, singular elements are applied at the crack tip.

Below, you can see some of the results from this simulation.
