You are called as an expert witness to analyze the fracture of a sintered silicon carbide plate that was fractured in bending when a blunt load was applied to the plate center. Measurement of the distance between the fracture origin and the mirror/mist boundary on the fracture surface gives a radius of 0.796 mm. You are given three pieces of the same SiC to test, and you determine that the mirror radius is 0.603, 0.203, and 0.162 mm for bending failure stress levels of 225, 368, and 442 MPa, respectively. What is your estimate of the stress present at the time of fracture for the original plate?
A cylindrical specimen of steel having an original diameter of 12.8 mm is tensile tested to fracture and found to have engineering fracture strength of 460 MPa. If its cross-sectional diameter at fracture is 10.7 mm. Determine the ductility in terms of percent reduction in area
Why is the prediction of the tensile fracture of a brittle material is difficult to predict?
specimen of a 4340 steel alloy with a plane strain fracture toughness of 54.8 MPa√m is exposed to a stress of 1030 MPa. Will this specimen experience fracture if it is known that the largest surface crack is 0.5 mm long? Why or why not? Assume that the parameter Y has a value of 1.0.
Some aircraft component is fabricated from an aluminium alloy that has a plane strain fracture toughness of 35 MPa√m. It has been determined that fracture results at a stress of 250 MPa when the maximum (or critical) internal crack length is 2.0 mm. For this same component and alloy, show that whether fracture will or will not occur if the stress level is at 325 MPa and the maximum internal crack length is 1.0 mm.
Do the irregularities vary from specimen to specimen in tensile fracture?
Estimate the theoretical fracture strength of a brittle material if it is known that fracture occurs by the propagation of an elliptically shaped surface crack of length 0.20 mm and that has a tip radius of curvature of 0.001 mm when a stress of 1450 MPa is applied. The question is attached. The answer is not 29000. WileyPlus marks it as incorrect.

NEED AN ANSWER ASAPAn aircraft component is to be fabricated from an aluminum alloy that has a plane strain fracture toughness of 45 MPa m and a yield strength of 500 MPa. It has been determined that fracture results at a stress of 250 MPa when the maximum internal crack length is 9 mm. For this same component and alloy, determine critical internal crack length that will result to fracture if the design stress is three-fourth of the yield strength.
