A manufacturer wishes to choose between two ceramics for a certain application. Data for the two ceramics tested under identical conditions were as follows: Ceramic Mean Fracture Stress Weibull Modulus A 500 MPa 12 B 600 MPa 8 The service conditions are geometrically identical to the test conditions and impose a stress of 300 MPa. By constructing Weibull graphs with S = 1/2 for mean fracture stress or any other method, decide which ceramic will be more reliable and compare...
