A ceramic part for a jet engine has a yield strength of 75,000 psi and a plane strain fracture toughness of 5,000 psiVin. 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 faws greater than 0.05 in. long. Assuming that f = 1.4, does our nondestructive test have the required sensitivity? Explain.

A cylindrical specimen of a steel alloy 10 mm in diameter and 100mm long is pulled in tension at a load of 23500N and the strain found to be 0.0015, the elongation will be: Select one: 0.15mm Ob. 0.023mm 0.100mm Od. 0.0015mm

A ductile specimen that has an initial length of 10 cm is tested under uniaxial loading.  If the test is under tension and the nominal strain is 21.9%,  please calculate the true strain in %.

A component made of 7075-T6 aluminum alloy has an edge crack of 1.4 mm in length. Plane strain fracture toughness of this alloy is given as 27 MPavm. Geometrical factor of the crack is given as 1.2. (a) If this alloy is subjected to uniaxial tensile stress of 380 MPa, determine whether sudden brittle fracture occurs or not. (b) Calculate the maximum allowable crack size for this component in order not to be failed in brittle manner under a stress of 1000 MPa (Density of steel 7.85 g/cm³, 9.80665 N = 1 kg).
