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 PMMA plate with a 25 mm (width) x 6.5 mm (thickness) cross-section has a contained crack of length 2c = 0.5 mm in the center of the specimen. If the applied load (along the 2 length direction) is 1000 N, calculate the stress intensity factor. If the fracture toughness of PMMA, K1c = 1.15 MPa.m1/2, at what load (in N) does the crack propagate?
