Study on Friction in Contact
Posted: 07 Mar 2023, 13:45
Performed an extensive study on friction between a block and a base. All files are here

There are a couple of videos that look like good solutions.
The normal force in the block is correct since the stress values and vertical down displacements are correct.
However, it is difficult to make sense of the reported contact values and the block always moves in the lateral direction regardless of friction coefficient used. In addition the results are the same regardless of friction coefficient used.
The first number is the value at a node in paraview, it is then followed by a boundary sum or mean, it looks like I should have used mean on the displcement contact normalload variable
The Friction Contact = Logical True would crash with a system error after 1 or 2 steps.
