Abstract
Analysed are only stress related and cyclic related safety factors. Stresses are calculated with FEM-linear and FEM-non-linear. Material data are based on Smith diagram or modified Goodman diagram. Recalculation of stresses are necessary for averaging and for correction of stress concentration. Two examples of safety calculations of power machines components, turbine blade and fan hub are shown.
Keywords: safety factors, stress, cyclic load, FEM, stress concentration factor
