Efficient implementation of critical plane for 3D stress histories using triangular elements

Abstract

Multiaxial fatigue and the application of critical plane criteria are briefly reviewed. Methods to increase the efficiency of such criteria are discussed. A simple methodology is also presented where the critical plane search space is discretised using triangular elements and adaptively refined. It is shown to increase accuracy in the damage search with fewer candidate plane evaluations, useful for large 3D models. Parallel computations are also leveraged.
