Commonalities and differences are brought out by comparing and contrasting their themomechanical characteristics, with examples. Emphasis is given to the role of design and the use of mechanism-based models of material behavior. Factors addressed include the relative significance of thoughness and ductility for thermostructural applications, including their manifestation in the notch sensitivity. The detriments caused by anisotropy are examined, through discussions of mechanisms such as delamination in CMC's and transverse debonding in TMC's."--Page 1 Notes A portion of the work done to prepare this document was performed under Department of Navy Contract N00014-93-C-0089 issued by the Office of Naval Research under contract authority NR 201-124 "The International Science Lecture Series (ISLS) operates as a special project of the National Research Council's Commission on Physical Sciences, Mathematics, and Applications.
