Has anyone seen this contact error before? I am having trouble understanding why the top plate is penetrating the core. The plate and the core are one part. I use power law plasticity for the material and the sphere is rigid. The sphere uses a automatic one way surface contact.
Is this problem more the contact or material? Or is there something else.
Hi,
This happens a lot when contacts are not defined properly. I have faced this problem few years ago when I ran my first Ls-Dyna model.
The reason why it penetrates is because it doesn't read that there's another surface thru which it needs to interact.
I'm pretty sure you haven't defined surface to surface contact between these two surfaces. Define it and let me know if you still l face same issue.
Shubham Mishra for shell elements, is it best to define the surface type as part ID, segment ID, or shell element ID?
Hi Chase Mortensen,
Add all the elements into two different sets. It helps us easily define the surf to surf contact between two set of surfaces.
Part ID can also be used but don't go to element ID, as there will be too many IDs of individual elements, it's not easy hence not preferable.
