In order for the event simulation to make any sense, the PC-ABS needs to be modeled as a non-linear material. The best way to do this is to duplicate the custom PC-ABS material in the favorites and change the advanced properties to plastic.

This allows for calculations to take place past the elastic limit of the material (point of yield strength) and into the region of plastic deformation. The plastic deformation region of the material represents the range in which the material endures unrecoverable change to its structure past the point of recovery.
