A large flat plate is subjected to constant-amplitude uniaxial cyclic tensile stresses of a maximum stress of 147 and a minimum stress of 32 MPa. If before testing the largest surface crack is 0.98 mm and the plain-strain fracture toughness of the plate is 33.4 MPa m1/2, estimate the fatigue life of the plate in cycles to failure. For the plate, m = 3.7 and A = 5.0 x 10-12 in MPa and meter units. Assume Y = 1.14
