Summary

 
This study is an alternative FEM-based fatigue strength calculation for propulsion shafts as per RS Rules. Direct numerical simulation yielded the fields of stresses and strains. Lifetime assessment was based on S-N fatigue model: critical stresses for this model were obtained as per critical-plane method taking into account non-proportional loading of propulsion shafts. It compares two shaft designs: in compliance with RS Rules and with deviation from them.
