Chapter 08, problem 8.11 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 101 () and a yield strength of 730 mpa (52940 psi). the flaw size resolution limit of the flaw detection apparatus is 3 mm (0.1181 (a) if the design stress is one-half of the yield strength and the value of y is 1.15, what is the critical flaw length? mm (b) on the basis of this value, is a critical flaw subject to detection? the tolerance is +/-2%
