Can MPM particles simulate the compaction effect

[808-code]

For example, if I step on a piece of soil, the soil will be compressed and become hard, and the existing MPM examples seem to fail to reflect this property

I have a WIP version of the MPM solver which among other things adds a sinh(det Fp) hardening model following [1], hoping to create the PR shortly. It would be great to know if that can be useful for your use case

Thank you, I am waiting to see
