Abstract
A numerical model is proposed for the cyclic life of a structurally in homogeneous powder material. The model is based on the mechanics of st ructurally inhomogeneous deformable media. The finite-element method h as been used to solve the boundary-value problem for deformation and f ailure in a microscopically inhomogeneous material under a external lo ad. The simulation indicates the effects of structural microscopic inh omogeneities (pores and solid inclusions) on the fatigue characteristi cs of PK-100N4M powder low-alloy steel, and die fatigue working-life c urve is derived.
