Properties and Performance of Ceramic Composite Components

“…As an example of the technique, we compare the results obtained from using the DS bridging expression to the results from an earlier expression from Marshall, Cox, and Evans (MCE)8,-namely For unidirectional dense alumina p'"'=[4a2Ef+T' (9) fiber/alumina-yttria matrix composites at room temperature, q is found experimentally to be 3.56. The normalizing stress, 00, is the ACK cracking stress, 458 MPa.…”
