Comparison between data generated from 'standard' fracture toughness specimens and from nonstandard specimens made of a silicon carbide.

摘要

The ability of methods based upon linear elastic fracture mechanics to predict the structural integrity of a class of monolithic ceramics was investigated experimentally. Three important assumptions related to the hypothesized methodology are identified for verification. The data and discussion presented in this report provide strong support for all three. Obstacles to be overcome in the final design/assessment of a structural ceramic component are also identified. 7 refs., 4 figs.
