Consider a large, flat plate of a metal alloy that is to be exposed to reversed tensile-compressive cycles of stress amplitude 150
MPa. If initially the length of the largest surface crack in this specimen is 0.75 mm and the plane strain fracture toughness is 35
MPa. m^((1)/(2)), estimate the fatigue life of this plate. (Y=1.75,m=2.5,A=2\times 10^(-12))
