I am simulating crashworthiness under oblique loading. Both the contact surfaces(one being rigid and the other modeled using solid elements) are supposed to be at an angle. However, the body with the solid elements always rotates just before the contact begins, such that the contact surfaces become parallel. How to avoid this? Which contact type is to be used? I tried with Automatic Surface to Surface, Automatic General and Automatic Nodes to Surface without much success. Does the type of solid element also affects this?
Hi,
This is a contact problem between a rigid and deformable bodies I supposed. You can use either the surface to surface or automatic general.
If understand correctly, your deformable body rotates due to the contact such that the final contact is parallel. If this is the case, the problem is then on the boundary condition of your deformable body. You need to constrain its rotation at some nodes... did you constrain it correctly?
Yes, you have understood it correctly.I did apply a rotational constraint but not at the nodes in contact. It still rotates. Any other suggestions?
Thanks.
