I try to simulate a particle impact on a substrate with certain speed. How can I define a adhesive criteria, or adhesive behavior so that I can let the particle get stuck into the substrate rather than rebound in each time?

Based on common senses, particle would produce plastic deformation during the process of impingement, if the particle impact on the substrate beyond certain velocity, it might stick on the surface of the substrate.

I know this function could be realized in ABAQUS and LS-Dyna, while now, I only have component system Explicit Dynamics in Workbench and AUTODYN.

Therefore, especially, how can I realize this behavior in Explicit Dynamics?

Thank you.

As far as I can see and you have experienced there is no sticky type of contact like you have/mention in abaqus (cohesive interaction) in ansys explicit.

It seems that you mistake me. I mean I want to find such a way in Workbench/Explicit Dynamics, not in ABAQUS software.

By the way, through reading paper, I think you could define cohesive zone model or cohesive behavior in ABAQUS to realize it. Maybe the mistake origin from my poor English

This is a ansys forum so we can only comment on ansys products. So:

There is no sticky/cohesive contact in ansys explicit (autodyn).

Thanks for your answer. Is there any possibility for me to define a function inside of ansys explicit?

Not sure about that -
