A continuum approach for anisotropic fatigue is described. The approach is based on the idea of a moving endurance surface in
the stress space where the movement is described by a back-stress type tensor. The evolution associated with the movement is described by
a rate type equation. In addition, damage accumulation is governed by a rate type evolution equation, thus facilitating its use under arbitrary
complex loading conditions. The main emphasis of this paper is to discuss the possible forms of the endurance surface and pertinent
evolution equations to model high-cycle anisotropic fatigue. Suggestions towards a unified model capturing the low-cycle regime are also
given.
