Calculate the final critical surface crack length if the fatigue life of a material with a Kic of 25 Mpa m1/2 must be a minimum of 6.6 x 105 cycles. Assume the initial maximum edge surface crack to be 1.1 mm and the maximum tensile stress of 137MPa. Assume m=1.3, and A = 7.5x10-13 and Y = 1.19. The answer should be in mm with 2 decimals of accuracy.
