Rigid bodies intersecting

Rigid bodies intersecting

Rigid bodies intersecting

(OP)
I have a number of rigid bodies impacting onto a deformable body.

I'm using Explicit & general contact. I used the rigid body constraint to define the rigid bodies.

The contact with the deformable body looks fine but the rigid bodies just seem to pass through each other. How do I stop that?

NOTE: due to the number of rigid parts defining contact pairs is not an option.

RE: Rigid bodies intersecting

What kind of rigids are you using? Analytical?

RE: Rigid bodies intersecting

(OP)
Abaqus 14.1

The parts are rigid shells R3D3.

I thought that you could do DEM like modelling in Abaqus, is this not the case if rigid-rigid contact is missing?

RE: Rigid bodies intersecting

Should work. Maybe your mass is too low to calculate proper penalty stiffness.

RE: Rigid bodies intersecting

(OP)
Yes its looking like a mass issue thanks.
