abstract

In non-proportional multiaxial fatigue, principal directions of strains and stresses change during a cycle. In such a case, strain and stress ranges and mean strain and stress cannot be easily determined. Developing an appropriate method of determining the ranges and mean values are needed for the design of pressure vessels. This paper proposes a method for calculating the strain and stress ranges and mean values in non-proportional multiaxial loading. Based on the method proposed, non-proportional strain and stress ranges are derived and the accuracy of life prediction method using the ranges is discussed for type 304 stainless steel fatigued under 14 non-proportional strain paths.
