How to: Stress Concentrations on Shafts
Any abrupt change in parts can capture internal stresses and cause stress concentrations. Examples of these changes are the following: grooves holes notches shoulders keyseats threads splines The stress concentrations are localized… Continue reading
How to perform a Pressfit Assembly Process Simulation
Intro A novel approach of the assembly process of a pressfit is shortly presented. A pressfit is a method of fastening between two mating parts. The parts are pushed together and are hold… Continue reading
