dc.description.abstractSeveral theories have been proposed to describe the mechanical behavior of porcelains, all of which suggest that the behavior of porcelain is inconsistent with brittle failure theories. The literature demonstrates that the mechanical properties of porcelains are frequently measured without the measurement of elastic properties. When the elastic modulus and fracture surface energy are incorporated into the strength data analysis, porcelains behave in a perfectly brittle manner, indicating that the proposed theories describing the mechanical behavior are unnecessary. This work shows a direct correlation between stress at failure and elastic modulus of quartz and alumina porcelains with a uniform flaw population. Weibull statistics along with fractography indicate a single flaw population of quartz grains at the tensile surface ranging between 50 and 80 μm for both porcelain bodies consistent with the calculated flaw size. Real time age effects on strengths were found to be non-existent and cyclic exposure to high-pressure steam caused unglazed test specimen to significantly increase in strength. All findings indicate porcelains behave in a classic linear elastic manner.en_US
