000015434 520__ $$2eng$$aThe paper describes the constitutive model of discontinuous plastic flow (DPF, serrated yielding), that occurs at extremely low temperatures. A physically-based constitutive description of material behaviour, including damage evolution of mechanical and radiation origin, has been developed. The stress serrations are evaluated on the basis of changes in dislocations density, instead of a phenomenological unobservable function of state parameters. The mechanical damage description is based on the Lemaitre-Chaboche approach, whereas, the postirradiation damage evolution is based on the Rice and Tracey evolution law for the size of clusters of micro-voids.
