| Outline of Final Research Achievements |
It was confirmed that a discontinuity is clearly formed on the load-displacement curve of the Si-SiC type high porosity porous material (skeleton structured ceramics), resulting in apparent discrete destruction. Focusing on this discrete destruction, ultimately in a series of research aiming at construction method and lifetime prediction method, this research aims at Si-SiC skeleton structured ceramics and applies acoustic emission (AE) , the destruction mechanism of skeleton structured ceramics were revealed.
