Dear colleagues,

I need some help with FEM modeling with Abaqus.

My model contains three parts. The first is a support plate. The second and third part a fastener clip and a rail. As the fastening is deformed to fit the rail, in the first step I need to deform it so that it is in the correct position (the support plate and the fastening are connected by Tie constrain).

After this, a second step should be created to "release" the clip so that it contacts the surface of the rail, generating stress due to its initial deformation.

I've tried doing imposing a dislocation with the use of boundary conditions, but it has not worked.

Can anybody help me? Thanks in advance.
