The process of brittle fracture in a solid is presented as the formation and evolution of an ensemble of elementary carriers (frustrons). The latter represent a mesoscopic region of localized strong shear deformations surrounded by an envelope of an elevated level of plastic flow. The conditions of fluctuation generation of frustrons, their characteristics, and the growth of the supercritical cluster are determined. The fracture time is derived.
