Hi

My objective is to simulate cutting of soft bodies such e.g. food(vegetables), sponge, rubber etc with cutter/knife.

To start with I simulated cutting with very thin solid block (knife) and general flexible beam as soft body.

I tried to use spatial contact force for measuring contact force while cutting operation but since flexible beam is true geometry it cannot be used.

I am looking for pointers for how to measure contact force during cutting operation.

Have you given a read about the modelling of flexible bodies? PFB link
