A UNIFIED STATISTICAL THEORY OF STRENGTH O SOLID BODIES,

Abstract

The present work has as its aim the development of a unified theory of strength which can be used both in the mechanism of fracture and to derive a single set of conditions of strength which will fit all stress states. By applying statistical mechanics to a model of a quasiisotropic single-phase polycrystal, it can be demonstrated that the modulus of distribution of volumes V of crystallites according to stresses is a function of the external load. This circumstance is utilized to provide a unified explanation of cleavage fracture caused by tension or compression of brittle bodies; the fracture occurs through the action of tensile stresses.
