The Express Method of Determining the Fracture Toughness of Brittle Materials

Abstract

This paper presents a novel method of fracture toughness determination, - a method that does not require introduction of an initial crack or notch-type defect in a sample. The corresponding formula for calculating fracture toughness, which does not depend on crack length is derived. This “express” test is useful for industrial applications because it economical and may be used for a wide range of brittle materials from ceramics to concrete and rocks. Test results are shown to be in good accord with the results obtained by ASTM methods.
