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