Radiation Induced Damage in Ductile Materials Subjected to Time-Dependent Stresses

Abstract

The problem undertaken in the present work concerns the kinetics of evolution of radiation induced damage under mechanical loads. Furthermore, coupling between the radiation induced nanodamage and the mechanically induced micro-damage is taken into account. The evolution of radiation induced damage is combined with the evolution of classical mechanically induced damage within the common framework of Continuum Damage Mechanics (CDM). Closed form analytical solutions for the problem of periodic irradiation combined with cyclic axial loads, corresponding to Rice & Tracey law was obtained.
