Hi everyone, I am doing high velocity impact analysis on axisymmetric model which have ceramic (MAT_110) and composite (MAT_22) material and being impacted with tungsten projectile.

I am using mxeps as the erosion criteria and hourglass 6 (QM = 0.2). Also for delamination, I am using Constrained_tied_nodes_failure between ceramic and composite layers.

My results are not matching the published results and i can clearly see the error but dont know how to solve it.

Please help me resolve the problem.

Thanks and regards
