Hello!

 

I'm conducting gasket compression simulation like attached picture.

 

I applied friction condition with coefficient 0.3 between components boundary.

 

And, y directional displacement applied at upper component to implement gasket compression.

 

As a result, gasket deformation data but geometry overlap occured in white circle at attached picture.

 

How can I fix it?

 

Regard.

Hi

See our courses for some help perhaps:

Also perhaps you need some remeshing as it deforms and mesh is skewed.

Hope this helps

Hello Erik

I'll see you gave and operate analysis with remeshing.

Thank you for replying!

It looks like the contact definition only selected the flat top of the body and did not include the blends on the corners or the sides.  Or if the blends were included, the Pinball Radius was too small and did not pick up all the nodes around the corner.

Hello peter!

I conducted simulation without blends

But, I solve problem by setting pinball radius option from your advise.

I got result without overlapping!

Thank you for applying!
