I am doing a ballistic impact simulation, with a comparatively rigid bullet material to a deformable target material. I chose solid element for bullet and shell element for the target.
I am trying to use Constrained_Tied_Node _Failure for my impact simulation so as to have node splitting at the crack propagation.I have tried to constrain nodes on the surface of the target. However, I am getting an error "Tied nodes connected to multiple elements".Could anyone help me in my settings
Hi @navya-gara,
So you are trying to model crack propagation along the red part? Constrained_Tied_Node _Failure can only be used when you are trying to make the connection between two non-connected elements fail. You cannot use this with elements that share nodes like that red part. You should look into ways to model crack propagation within your material model or using something like *Mat_add_erosion.
What material are you using for the red part?
