LS DYNA ICE MODELING

recently, I use MAT_155 for ICE modeling. which was established by NASA.

The material parameter of mat 155 comes from the literature "A High strain

rate model with failure for ice in LS DYNA". And my product is an ice

plate impacting on a concrete column.

  But something is wrong in my simulation. The result of the ice plate

shows that, there is only X-stress, Y-strees and Z-stress. and they are

all equal. But the XY-stress,  XZ-stress, YZ-stress, are zero. The feature
