We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

I am trying to simulate a stress analysis of a screw screwed into a piece of bone. The constraints are to fix the bottom of the bone and allow rotation around the y-axis at the bottom of the screw. I first set a torque of 2N/m on the six internal surfaces of the screw and the results are shown in the figure. After that the other conditions did not change and I changed the torque to apply 0.02 rad/s to the screw as a whole, but the results did not change . Until I changed the normal contact stiffness from 0.5 to 0.1 and the stress maximum from 556MPa to 568MPa.
