Hi everyone, 

I am currently working on crack propagation in a crush thin-walled tube using Abaqus. to Simulate this, it requires using dynamic/explicit step. I have created the model and use a notch to create aan Initial crack, after Impact, I believe the crack suppose to propagate due to the wave cause by the impact. But XFEM is not available for dynamic/explicit step.

I will be glad fir anyone who knows how I can go about it.
