nI don't use any joints. Realistic (bonded for threads, frictional elsewhere) contacts are used for each interface.nThe rotational motion of the crankshaft is imposed by the Velocity BC. The case was initialised from Rigid Dynamics results.nThe piston head is constrained by a typical Displacement support.nThe symmetry condition is imposed by another Displacement support.nThe stresses in the model are high (up to a few GPa), but still I thought this grid is fine enough to inhibit hourglassingn
Te stresses in the model are high (up to a few GPa), but anyway I thought this grid is fine enough to inhibit hourglassing...nShould I enable plasticity (bilinear model)? If so, is it advisable to refine the grid even further?n
