WebJun 1, 2024 · The Dang Van criterion is a multiaxial high cycle fatigue criterion that considers the stresses in the meso and micro scales and is widely used for cases where residual stresses are present [14], [19]. This criterion considers shear stresses as fatigue initiators and hydrostatic stresses that favor crack opening as main parameters.
