Abstract

The expected fracture plane can be determined according to the critical plane approach and the fatigue life of a body under multiaxial loading can be calculated. A critical plane method recently proposed by the authors consists in averaging the instantaneous values of the three Euler angles, which describe the principal stress directions, through some suitable weight functions to take into account the main factors influencing fatigue fracture behaviour. Such a method is applied to a number of experimental biaxial proportional and non-proportional sinusoidal stress states.
