Is there any model for the simulation of solid tensile test ?

I had a student do a simple bending problem but he never sent a PR for this. :( I am more careful these days. Unfortunately, I don't think there is an example currently, if you do have one please do share it.

cheers,

Hello, I'm currently trying to implement Gray et al.'s (2001) SPH elastic dynamics problem (the tensile bar example) in PySPH, but I'm experiencing stability issues where the simulation breaks prematurely or shows unphysical fractures. I've tried adjusting artificial stress parameters and time steps, but the results remain unstable.

Have you successfully implemented your solid tensile test? I would be extremely grateful if you could share
