Abstract

Improving the fracture strength of ceramics has been one of the most important concerns in the ceramics field, and highly accurate evaluation of the fracture strength of ceramics is the right foundation of this topic. In this paper, we analyze fracture strength by using a previously established temperature-damage-dependent strength model. Sensitivities of fracture strength to relative parameters are analyzed, and the influences of different failure modes and typical sizes of different micro-structural characteristics on the fracture strength of ultra-high temperature ceramics (UHTCs) are discussed. This study can provide a theoretical basis and technical platform for the design, application and reliability assessment of UHTCs in applications.
