Creo Simulation 4
Hello,
I am trying to simulate the deformation of a plastic part when applying a force on it.
My goal is to check the pressure homogeneity on a custom made pick-up tool. I have the 3D design, I can setup the load on the surface, but I cannot define the real constraint.
If I lock the pressed surface , what I see is a 0 deformation of the surface and a homogeneous pressure applied, but the stress on the edges of the part, linked to the fact that the edges want to deform but cannot because of the constraint I have setup.
If I setup only a small part of the surface as a constraint, the entire part is deforming in the force direction.
What I need is a way to set up, or simulate, a planar constraint that allows the part to go only in the negative direction of the plane and not in the positive direction.
Do you have any suggestion about this simulation and how it could work?
Thank you very much!
Giando
