Hi,
I am new to Ansys and I am trying to simulate pulling two curved beam, joined at one end point, straight and during the process, the beams will touch one another. I am having trouble trying to assign some kind of contact or interaction (hard contact, rough surface) so that the beams don't go through one another when touching. I read online there is a line-to-line contact element 176 and 170 but I am not sure how I can assign it in the workbench. The following is what I've done:
I am doing this in Ansys 13 workbench.
My geometry is created as follows:
1) created two 3D curves (in the xy-plane) by reading external coordinate files;
2) a single line body is created by the workbench from the two 3D curves (because they join at the origin) and assigned a rectangular cross section to the line body to make it into a beam (does this actually make the line body into a beam element or do I need to explicitly assign it somewhere)?
Model:
I could find contact setup under "connections" --> contact but that seems to require two surfaces which I cannot select from my beam formed by the line body.
I know I probably can get this done if I actually create a 3D solid and assign contacts that way but I'd like to reduce the computation load if possible.
Could someone please give some pointers on how this can be done?
Thanks.
