Reply To: why calculations are the same for different load sizes or types

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.
