Contact Surface Problem - No Contact
Contact Surface Problem - No Contact
(OP)
I am trying to simulate a forming process with a rigid punch and a deformable material. I have defined a master/slave contact surface interaction with penalty friction attributes. The problem, is that when I run the simulation results, the rigid punch does not contact the deformable body. Instead, it passes through the body. Has anyone had problems like this or no of something I may be doing wrong?
Thanks for the help,
Chris

RE: Contact Surface Problem - No Contact
- Contact pairs defined correctly with *CONTACT PAIR keyword. This is defined as model data in Standard, step data in Explicit. Having said that, if your model is 3D Explicit, you can use the *CONTACT general contact method.
- Check the normal directions of the surfaces. You can do this in Viewer (Common Option I think). The surface normals must 'point' to each other.
- You can check the status of the contact pairs by adding *PRINT, CONTACT=YES in the step definition. Youu can then check the .dat file for information about whether the surfaces are initially opened or overclosed.
