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

A relatively large sheet of PC is to be exposed to cyclic tensile and compressive stresses of magnitudes 30 MPa and 20 MPa, respectively. Prior to testing, it has been determined that the length of the largest surface crack is 1.0 mm. Estimate the fatigue life of this sheet if its plane strain fracture toughness is 2.5 MPa√m and the values of m and A (in Equation 9.26, Callister & Rethwisch) are 3.0 and 1×10-12 , respectively, for Δσ in...
