Static Mesh Collisions Under Simulate Physics

I have a set of static meshes with simulate physics applied to them. These meshes I have designed and want them to pass through each other. Under some circumstances they seem to pull through each other and pull apart under high velocity situations. Ive tried using physics constraints, and adjusted the physics settings every which direction to dampen and limit them. But they still pass right through each other. What kind of options are there that might help me make these ring static meshes interact with each other under physics with out passing through each other. Are there some sort of blueprint tricks I could use?
