Abstract
An improved multiaxial high-cycle model based on the Gough and Nishihara & Kawamoto approaches is presented. The proposal is a compromise between the measure of the equivalent shear stress amplitude, obtained from a prismatic convex hull method, and the amplitude of the first stress invariant. This makes the criterion an effective approach to predict quickly the failure initiation for wide range of materials (from ductile metals to extremely brittle metals). The results obtained from our proposal are compared to experimental data reported in the literature.
