Hi
Any one who has performed or knows rigid body contact analysis using different coefficient of restitution and penalty method.
Any help will be appreciated.

RE: coefficient of restitution in abaqus
If you mean in ABAQUS, rigid bodies cannot contact with each other as far as I know.

RE: coefficient of restitution in abaqus
I have ran the analysis using rigid body general suraface contact for collison among different bodies. Because of the rigid bodies and general surface contact, the analysis results are more like perfect elast collison (perfect rebounce). In reality it will be between perfect elastic and perfect plastic. How can I change this rigid body surface contact to represent more like real situation.
thanks.

You could look at fooling around with some of the contact properties, such as pressre-overclosure (section 30.1 in the ABAQUS Users Manual)?
