6. A ceramic part for a jet engine has a yield strength of 648 MPa and a plane strain fracture toughness of 8.49 MPam. To be sure that the part does not fail, we plan to ensure that the maximum applied stress is only one-third of the yield strength. We use a nondestructive test that will detect any internal flaws greater than 0.27 mm long. Assuming that the Y constant is 1.4, does our nondestructive test have the required sensitivity? Explain.
