creating self contact and interfaces during impact analysis
Dear All,
I have created the self contact and interfaces in the impact analysis but the body is penetrating the rigid wall during the simulation in the hyperview.
i had followed the tutorial RD-3530: Buckling of a Tube using Half Tube Mesh
i can,t able to find the mistake done by me.
Kindly provide your guidelines
Thanks
Ram

Ram,
Symmetric BCs are used to simply the model to save computation time.
If you think your model is symmetric then you can use symmetric BCs which is not required in your case.
If you look at the tutorial problem, it is a hollow quad tube and it was cut into half and mounted with symetric boundary conditions to simply the FE model, thus reducing number of DoFs and computation time.
Hi Ram,
Please share the model file using the drop box link in my signature.
