A large flat plate is subjected to constant-amplitude uniaxial cyclic tensile and compressive stresses of 120 and 35MPa, respectively. If before testing the largest surface crack is 1.00 mm and the plain-strain fracture toughness of the plate is 35 MPa vm, estimate the fatigue life of the plate in cycles to failure.
