Strength-Size Relationships in Ceramic Materials: Investigation of Pyroceram 9606

Abstract

This research was directed to characterizing and explaining strength- size relationships exhibited by ceramic materials. Precise measurements of the strength of the commercial glass-ceramic, Corning's Pyroceram 9606, are reported. Fracture stresses in specimens differing in each linear dimension by a factor of five were measured at room temperature under carefully controlled conditions which minimized subcritical crack growth. Data obtained were analyzed with the aid of fractographic examinations to determine applicability of various size-effect theories. Findings indicated validity of the spurious-effect theory, and that the strength of Pyroceram 9606 can be described adequately in terms of stress alone. Maximum tensile stress criteria for failure were determined.
