Uniaxial tensile tests were carried on a ceramic. The following strength values were obtained:
310, 380, 400, 415, 448, 455, 475, 489, 500, and 502.
a. Calculate the probability of survival or probability of failure for these data. What is the Weibull modulus? Also calculate the characteristic strength.
b. What is the tensile strength at survival probability? If the volume was increased three fold, what would be the new strength value at survival probability?
