In designing a ceramic part for a jet engine, to ensure that the part does not fail, we plan to ensure that the maximum applied stress is only one-third of the yield strength. The yield strength of this CMC part for a jet engine is 520 MPa, and its plane strain fracture toughness is 5.5 MPa√?. We utilize a nondestructive test to find any internal faults that are longer than 1.27 mm. Does our non- destructive test have the requisite sensitivity if Y = 1.4? Explain

Question
In designing a ceramic part for a jet engine, to ensure that the part does not fail, we plan to ensure
that the maximum applied stress is only one-third of the yield strength. The yield strength of this
CMC part for a jet engine is 520 MPa, and its plane strain fracture toughness is 5.5 MPa√?. We
utilize a nondestructive test to find any internal faults that are longer than 1.27 mm. Does our non-
destructive test have the requisite sensitivity if Y = 1.4? Explain.
