Notes:
The paper deals with crack formation of thermal stresses in an isotropic multi-particle-matrix system of homogeneously distributed spherical particles in an infinite matrix divided to cubic cells containing a central particle. Originating during a cooling process as a consequence of the difference in thermal expansion coefficients between a matrix and a particle, the thermal stresses are thus investigated within the cubic cell and extreme at the critical particle volume fraction. Resulting from the derived crack formation condition related to an ideal-brittle particle, the critical particle radius considering the critical particle volume fraction is presented along with an application to the thermalstress- strengthened SiC-Si3N4 ceramics
