Penetration master slave surface mesh size
Penetration master slave surface mesh size
(OP)
Hi everybody!
In a contact analysis in Abaqus, you should always have a denser slave surface than master so you don't experience penetration. I found this picture to illustrate: https://www.sharcnet.ca/Software/Abaqus/6.11.2/boo... .
I use a 4-node shell element mesh (R3D4), in contact with a solid 3d 20-node brick element. In contact it means the 20-node brick in the plane have 8 nodes against the 4-nodes in the shell elements. Do I then need to have a four times finer mesh in the shell elements then in the solid elements? If this was understandable?
Thanks for every input!

RE: Penetration master slave surface mesh size
Use general contact or surface-to-surface contact pairs. These formulations also reduce the mesh density issue.

Also you may want to think about using linear bricks instead of quadratic ones for contact.
