A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane strain fracture toughness of 103 () and a yield strength of 710 MPa (51490 psi). The flaw size resolution limit of the flaw detection apparatus is 3 mm (0. 1181 in. ). (a) If the design stress is one-half of the yield strength and the value of Y is 1. 18, what is the critical flaw length
