ABAQUS VUMAT large kinetic energy during analysis

ABAQUS VUMAT large kinetic energy during analysis

ABAQUS VUMAT large kinetic energy during analysis

I’m trying to simulate 3D cutting process of Carbon Fiber Reinforced Polymer (CFRP) composites in ABAQUS explicit, dynamic. I am using a subroutine VUMAT which includes material definition, HASHIN failure criterion and progressive damage model. I have changed almost everything including geometry, boundary conditions and time increment (also amplitude). Most of the time I get extremely large kinetic energies and the analysis is aborted due to excessive element distortion. Would you please take a look at the input file (CAE file) and the subroutine?
