Modeling of scattered damage accumulation kinetics under combined stress

An analysis of the reliability and range of application of a number of phenomenological damage models has been performed on the basis of experimental research carried out into the kinetics of damage accumulation in metallic structural materials under plane stress and active loading. Damage models are based on the main postulates of irreversible thermodynamics and continuum damage mechanics. The laws governing the effect of the type of stress state on scattered damage accumulation kinetics have been established.
