Question
A ceramic part for a jet engine has a yield strength of 66,215 psi and a plane strain fracture toughness of 5000 psi (in) ¾. To be sure that the part does not fail, we plan to assure that the maximum applied stress is only one-third the yield strength. We use a nondestructive test that will detect any internal flaws greater than 0.05 in. Iong. Assuming that f = 1.2 , does our non- destructive test have the required sensitivity? Type 1 for yes and O for no.
