Torque required to shear titanium

[Farrell1]

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!

To calculate the torque required to shear the plate, you will need to calculate the shear stress on the plate using the equation: Shear Stress = Force/Area. Once you have this value, you can calculate the shear strength of the material (Shear Strength = Shear Stress x Shear Modulus). Then you can use this value to calculate the torque required to shear the titanium plate. The formula for torque is T=F.r, where F is the force and r is the radius of the platen. So, for your case, the force F would be equal to the shear strength of the material, and the radius r would be equal to the distance from the center of the platen to the point at which the force is applied.
