Refractories and Industrial Ceramics Aims and scope

Abstract

The relationship between elastoplastic strain and brittle fracture in very hard brittle materials is studied by the microindentation method. Forcing and energy conditions for the nucleation, incipient subcritical growth, and subsequent propagation of cracks initiated by a local stress concentrator (a diamond-tipped indenter) are examined for various materials.
