A mathematical model is presented to describe the combined timedependent and cycle-dependent fracture characteristics of devitalized cortical bone. Failure is interpreted based on a linear-life fraction rule, which accounts for cumulative creep and fatigue damage under arbitrary loading histories. T

In this article we consider a cumulative damage shock model under a periodic preventive maintenance (PM) policy. The PM is imperfect in the sense that each PM reduces the damage level by lOO(1 -b)%, 0 5 6 5 1. A system suffers damage due to shocks and fails when the damage level exceeds some thresho
In a recent study [15], we proposed a class of isotropic damage models which account for initial stresses. The present paper extends this approach to anisotropic damage due to growth of an arbitrarily penny-shaped microcracks system. The basic principle of the upscaling technique in the presence of
