Is it possible to combine Plasticity & Fracture?

[Andrey-Pavlov]

Have you found anything yet? I was looking for a similar implementation and found this and also nvidia flex, but none of developers respond

Nope. Nvidia & AMD don't care about us.

Obviously not. Similar simulations need to use MPM method, but this method has not been implemented in real time

Plasticity + Fracture should be possible. My experience was more with DMM, so I'll tell you what I know from that, but as far as I recall, FEMFX is similar in this respect. I would use a generous amount of tets first to make it a bit easier (off the top of my head, if you're doing a thin plane like above, I would use a couple thousand. Shouldn't be necessary, but it's one less thing to worry about).

Note that we had a problem with "spinning tets" when we combined fracture and plasticity. After fracture, the pieces with just a few tets would just spin, sometimes picking up energy, even, and then flying off. It was especially prevalent with thinner tets (one dimension much smaller than other two) - another reason you might try a bunch. We suspected it was the combination of a linear solver and the co-rotational method. I believe FEMFX uses the same two approaches.

Sorry my answer is almost 2 years late. Better late than never?
