Impact simulation in order to evaluate delamination in composite material (Abaqus)

Impact simulation in order to evaluate delamination in composite material (Abaqus)

Impact simulation in order to evaluate delamination in composite material (Abaqus)

(OP)
Good morning,

I am new and I would like to ask you some advice. I would like to create a model that allow me to visualize and evaluate delamination in a composite material. In the simplified model (just to get start) I created, I have two plies, a cohesive region and a ball. The plies are defined as solid part with material defined by engineering constant. The cohesive region is made up by cohesive elements, and the ball is defined as discret rigid part. I upload the CAE file, in this way you can visualize surely better. However there is a general contact interaction in explicit step. The Ball has a speed defined in.

The main questions are: why the rigid body (ball) pass trought the cohesive region? (I have defined an interaction of normal behavior with impenetrability) Why the cohesive region deform in that way? (protuberances going toward the z direction, and stress in some zones along the edges?)

Finally why also if I increase a lot the speed of the ball (in its mass center) the plies and the cohesive region deos not disapear? (I have selected in the mesh type: "delete deletion YES")

Thank you in advance for your help.
