Previously a stochastic model for damage accumulation was proposed to obtain an expression for the fatigue crack propagation rate. In this paper, the model is used in order to derive the creep crack propagation law. The theoretical results show a good agreement with the experimental data. This sugge
Abatmct-A new continuum damage mechanics-based model is proposed to describe cyclic creep behavior of selected engineering materials under complicated loading conditions. The loading conditions involve both load holding time and load dwell time. Besides the damage parameter used by most continuum da
## A cumulative damage theory is developed based on the concept of bounds on residual life. Previous results applicable to fatigue are generalized to creep-rupture and to creepfatigue interaction. By defining a creep endurance limit and void-initiation life fractions, a complete symmetry is establ
The evolution of primary creep is modelled by the formation of sub-cells in which a pattern of internal stresses exists. The internal stresses have two components, one a general isotropic impediment to dislocation movement, the other an elastic back stress leading to kinematic hardening. The stresse
