A theory of radiation effects in graphite based on a description of the evolution of an ensemble of microcracks as a result of radiation-induced shape-change of crystallites is constructed. Curves of the shape-change and change of the elastic modulus as a function of the irradiation dose are constructed, the scale effect is explained, and it is predicted that there is a dependence on the angle relative to the axis of orthotropy and that hydrostatic compression affects the sound speed in graphite.
