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.

Hi Ji Shiyu!

You can calculate the pretension force of the bolt using this formula:

T = K*F*d

Where,
T = Torque in Nm
K = Constant which is usually taken as 0.2 for normal dry conditions,
F = Axial bolt force or pretension force in N
d = Nominal diameter of the bolt in m.

To apply bolt pretension in Ansys Mechanical, you can use bolt pretension object.
