A statistical theory of transgranular brittle fracture for metals is discussed. According to the continuum model of interface energy describing the interaction between transgranular brittle crack and grain boundaries and nonequilibrium statistical theory of fracture,the crack growth rate,fracture strength,fracture toughness,brittle-ductile transition temperature and their statistical distribution functions changing with grain size and interface energy are derived in a unified theory.
