Abstract
This investigation revisits biaxial fatigue experiments carried out with nickel-based superalloy Waspaloy. Recently, yield criteria extended to multiaxial fatigue and stress-based approaches have been analysed, and their performances in correlating biaxial test data have been evaluated. It has been concluded that despite giving reasonable results, the parameters do not properly represent the physical behaviour of the material. An extension of the study is therefore executed using the strain based critical plane approaches proposed by Wang-Brown and Fatemi-Socie, and the energy-based approaches proposed by Smith-Watson-Topper, Liu and Ince-Glinka. Reasonably good fatigue life predictions are obtained with all criteria. However, for low cycle fatigue regime, best correlation is obtained with the Liu parameter.
