摘要: The knowledge of statistic characteristics in mechanical properties is important for designer order to asses the reliability structure. Scatter fracture strength (splitting strength) porcelain toughened by zirconia and effect sintering temperature were investigated this study. Many specimens tested Brazillian method obtain scatter data strength. probability distribution evaluated using Weibull ddistribution function. Fracture increased with content having highest value (43MPa) at 10 wt.% then decreased .The same behavior was modulus, (39) Zirconia . modulus also affected temperature, they increasing temperature.
