A structural component is to be made from 4340 steel in the form of a very wide plate. The steel has a yield strength of 1200 MPa and a plane strain fracture toughness of 80 MPa m1/2. Assume plane strain conditions exist. It is not possible to detect flaw sizes less than a=3mm (resolution limit of flaw detection apparatus). Determine whether or not a critical flaw is subject to detection. Assume that the design stress level (i.e., the maximum stress to which the component will be loaded in service) is half the yield strength and that Y is 1.0.
