Coupling solid mechanics with deformed geometry

Please login with a confirmed email address before reporting spam

Hello,

I am trying to create a 2D model where I have (for now) two shapes: a circle and a rectangular plate. Initially, the circle does not touch the plate. What I need it to do is to have the circle grow over time such that it eventually comes into contact with the plate and then causes it to deform.

So far, I've figured out how to make my circle grow over time using the Deformed Geometry interface (the guides and various online tutorials have been very helpful for this!) but I can't figure how to get it to cause the plate to deform? I'm assuming I need to set a contact pair between both shapes, but what BC do I need to use in the Solid Mechanics interface to have the deformation of the plate be dependent on the current size of the circle?

Thanks.

Hi Alexander,

You can also contact support@comsol.com, if you don't get an answer to your mechanical contact problem.

Hi Alexander,

The contact algorithm should take care of that automatically. When there is overlap between the circle and plate a contact force is internally applied that deforms the two bodies until the overlap is eliminated.
