| Abstract Scope |
Energetic particle irradiation creates point defects and leads to microstructural and micro-chemical evolution and phase changes in multi-component crystalline solids, all driven by defect transport and reactions. Such evolution processes manifest themselves in shape distortions and in mechanical property changes and environmental degradation. We present a general theoretical formalism of the radiation effects problem that has the potential to bridge mesoscale to the engineering scale via systematic averaging. This formalism treats the microstructural and micro-chemical evolution and phase changes in a unified fashion, while enabling the prediction of creep and swelling as macroscopic manifestation of the underlying evolution processes. This formalism is based upon the continuum theory of defects and non-equilibrium thermodynamics. Working within the framework of finite deformation of crystalline solids, we will show that intimate connection between crystal mechanics and all aspects of radiation effects. |
