How to simulate Free-Free boundary condition in Abaqus?

01 January 1970 1 1K Report

I have a plate with rectangular geometry and I want to simulate a free-free boundary condition

I try to do that with RP in the interaction module in Abaqus and I fail. I will be grateful for any help with this problem.

One trick that may work is to start the analysis with a plate constrained by elastic supports on all edges. Specify the stiffness of the elastic supports, then gradually reduce the stiffness values on all the edges. As the stiffness values approach zero, your result will approach that of the free free boundary condition.
