For a specimen of a steel alloy with a plane strain fracture toughness of 80 MPavm, fracture results at a stress of 510 MPa when the maximum (or critical) internal crack length is 6 mm. For the same alloy, will fracture occur at a stress level of 380 MPa when the maximum internal crack is 9.0 mm? Why or why not? Select the most appropriate answer based on your calculation. Select one: a. Not enough information b. It will fracture c. It will not fracture
