A microscopic theory of brittle fracture in deformable solids: a relation between ideal work to fracture and plastic work
ML Jokl, V Vitek, CJ McMahon Jr - Acta Metallurgica, 1980 - Elsevier
A criterion is developed for brittle fracture of a crystalline solid which is capable of being
plastically deformed. The theory starts with the experimental fact that during extension of a …
