Abstract

Plastic behaviour under tensile time independent conditions is influenced in polycrystalline materials by the role played by the internal damage. This phenomenon can be evaluated by means of some analytical damage rate formulations derived from the well known Kachanov equation taking into account the non-linear material behaviour. These relations have been applied to AISI-310 stainless steel (deformed by tensile straining at room temperature) by assuming as damage assessment the experimental relative variation in density due to the presence of voids or microcracks occurring during plastic deformation.
