Hi, I am trying to workout how much torque from a motor is required to shear Ti64 plate. I have an upper platen which is rotated by a motor. The upper platen is compressed against titanium plate at 19kN. I am simulating sliding during forming process and need a motor to be able to turn the upper platen agaisnt the titanium whilst heavily loaded. For worst case scenario I think it best to determine the torque required to shear the plate (ie the platen is completely fixed to the titanium plate). The shear modulus of the Ti64 is 42GPa. Any guidence would be much appreciated. Thanks!
