Wytrzymałość zmęczeniowa w warunkach złożonego stanu naprężenia – metoda płaszczyzny krytycznej

Fatigue strenght estimation method in two-dimentional stress is proposed. Formulation of the method is based on the assumption of critical plain depending on direction of mean stress. This fact enabled assumption of strength dependence on direction using relationship between mean value of stress cycle and fatigue strength. The proposed relationship was successfuly approved by experimental results.
