Multiaxial Fatigue Damage Models

Abstract: Two multiaxial fatigue damage models are proposed: a shear strain model for failures that are primarily mode II crack growth and a tensile strain model for failures that are primarily mode I crack growth. The failure mode is shown to be dependent on material, strain range and hydrostatic stress state. Tests to support these models were conducted with Inconel 718, SAE 1045, and AISI Type 304 stainless steel tubular specimens in strain control. Both proportional and non-proportional loading histories were consid… Show more

“…Further, it is hypothesised that, in order to correctly take into account the mean stress effect, according to Socie [22], not only the amplitude, σ n,a , but also the mean value, σ n,m , of the stress normal to the critical plane has to be incorporated into the fatigue damage model (Fig. 1b).…”

“…(2), the mean stress effect in fatigue is taken into account as suggested by Socie in Ref. [22]: it is evident that this assumption results in a great simplification of the design problem, so that, in what follows, fatigue damage is simply estimated by taking full advantage of Eq. (2).…”
