Contact problem in solid mechanic: sover don't convert
Posted May 6, 2013, 10:36 AM EDT Structural Mechanics & Thermal Stresses 6 Replies
I want to simulate a screw in a boneblock which is bonded with a force vertical to the screw axis (see picture). The two blocks are a union with differend materials. There are used 3 different materials: the screw, the cortikalis (smaler block) and the cancellous bone (bigger block). In Finish I've form an assembly, activated Create pairs and the Pair type is Contact pair. I 've create a contact pair between the srew surface an the bone in Definitions. In boundary conditions I've assign the Contact Pair and the load in the screw head. The bone surfaces are fixed Constraints. A free tetrahedral mesh is used.
I used the stationary solver, solved in the direct way with MUMPS and fully Coupled. But the Solver don't convert.
Maybe the solver is wrong for this probem or I've forgot something. Can you please help me?
What is the best solver for my contact problem and what I did wrong?
Thank you for your help
