Hello,
I am performing numerical simulations of the axial-compressive test of cold-formed steel-lipped channel sections (stud) connected to a small length of U sections (track) at both ends with self-tapping screws under axial-compressive loading (displacement-controlled loading along the length of the stud-i.e, z direction in Abaqus model). I have introduced contact interaction between the stud and track through a general contact algorithm. In the normal direction, I applied hard contact, and in the tangential direction, I applied the coulomb frictional coefficient through the penalty friction method. The picture of the model is attached herewith.
My question is:
Is there any way to define the in-plane stiffness of the contact elements? How I should do that? Any possible help or direction towards finding the answer to my query is highly appreciated!
