Multiaxial Fatigue Criterion for Notched Specimens Including the Effective Stress Range, Relative Stress Gradient, and Hydrostatic Pressure

Materials Science Aims and scope

Abstract

Multiaxial fatigue criteria for notched specimens must take into account the equivalent stress range, the relative stress gradient, and hydrostatic pressure. The effective shearing stresses take into account the relative gradient via the weight function. As a result of testing notched specimens of mild steel under combined torsion and tension, it was established that the effective shear stresses are linearly decreasing.
