Finite sliding contact inAbaqus

[mihaimec]

Hello,

Can someone tell me please how to set up a finite sliding node to surface contact so that I can take in account the shell thickness.

For example let's say there are two plates with a thickness of 5mm and the distance between them is 6 mm.
How can I formulate a contact between those two. I take in account the initial gap of 1mm by using
*CONTACT INTERFERENCE

Thanks a lot,

Mihai

Read the manual. Finite sliding + node to surface can not use the shell thickness in contact. Switch to surface to surface.

Node to surface finite sliding do not take into account the shell thickness, not that it can not use it. I need a workaround and I have already checked the manual for the basis topics.

Is there a question hidden in your post?

Two methods I have used, but probably only the first is relevant to you:

1) Tabular pressure-overclosure defintion with negative overclosure(=positive clearance) to force contact to occur at an offset. For example:
*surface behavior, pressure-overclosure=tabular
0, -0.5
10, -0.25
50, 0
100, 0.5

2) Explicit only: *Contact clearance and *Contact clearance assignment. This is useful in cases where explicit scales the contact thickness.
