Question: 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

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 77.0MPα√m (70.1ksi√in) and a yield strength of 1400MPa (205,000psi). The flaw size resolution limit of the flaw detection apparatus is 4.0 mm (0.16 in.). If the design stress is one half of the yield strength and the value of Y is 1.0, determine whether or not a critical flaw for this plate is subject to detection.
