Rigid body
Rigid body
(OP)
Hello Friends,
I would like to make a cylinder behave as a rigid body (showing no stresses in itself when it hits another body). Please help me out in detail how to go about with this. Various methods would be good so that I have more than one way to do this. Thank u all for ur favor.

RE: Rigid body
If you have a contact problem (as I understood) you must have only the contact area defined and with the help of contact wizard you will define a rigid-flexible contact selecting for the rigid part the contact area. I think this is the suitable way for your problem.

I try to complete my advice. Follow this advice and you could define pilot nodes it means nodes that control the behaviour of DOF's of the entire rigid body. You could impose in these pilot nodes displacements what you need and you will have good result. Once again you need only to define the external (contact) area of rigid body and use the contact wizard.

RE: Rigid body
I presume it is a Contact analysis problem.Another method of creating a rigid body is constrain it in all the the avialable dof and insted of it hitting the body let the body hit it.If possible set the density and poissions ratio of the body abnormally high.
