PMMA ABAQUS Modelling

Hello guys, I'm trying to simulate planning cutting. I'm using a diamond tool (rigid body); however, for the workpiece, I want to have PMMA. Currently, the material properties for the workpiece are for aluminum using Johnson-Cook failure mode.

Can someone help me set up the material properties for PMMA? and how would I need to change for the simulation (failure mode)?

Thanks
