# Calculation of torque from friction force between 2 contact surfaces--------------------------------------------------------------QUESTION:Do you have an example illustrating a procedure for simulating a swaging operation? I want to simulate the operation itself and then perform a "virtual test" to see if the friction in the swage joint can support a certain amount of twist imposed on the end of the shaft.ANSWER:See the attachment to this solution. An axisymmetric part with hole slightly larger than the shaft is swaged onto the shaft. The pressure causing the swaging is removed, and the tip of the shaft is twisted one full degree.
