Hello,
I am working on Self piercing riveted joints and trying to simulate using Lsdyna,iam using piecewise linear plastic material model. The rivet is not able to pierce into the sheets, insted it is compressing the elements and elongating them. 4-noded shell elements where used. i want to know how will the elements get broken up or removed from the path of the rivet, I have used one way erode contact card but it was of no use. If any one can suggest me how the approch should be i would be a great help.
