A structural component is fabricated from an alloy that has a plane strain fracture toughness of 45 MPa √ m . It has been determined that this component fails at a stress of 300 MPa when the maximum length of a surface crack is 0.95 mm. What is the maximum allowable surface crack length (in mm) without fracture for this same component exposed to a stress of 300 MPa and made from another alloy with a plane strain fracture toughness of 57.5 MPa √ m
