Calculation of multi-layer interference fits

A multi-layered interference fit under optional internal and external pressure is calculated considering rotation speed and temperature.
These online calculations are provided free of charge by MESYS AG. The software is tested and no errors are known, but there is no warranty for the correctness of the results and for the availability of the calculations. The usage is at own risk.
