Alarge, flat plate is subjected to constant-amplitude uniaxial cyclic tensile and compressive stresses of 120 and 35 mpa, respectively. if before testing the largest surface crack is 1.00 mm and the plain-strain fracture toughness of the plate is 35 mpa √ __ m , estimate the fatigue life of the plate in cycles to failure. for the plate, m = 3.5 and a = 5.0 × 10−12 in mpa and m units. assume y = 1.3.
