Consider a compact specimen that is loaded cyclically at a constant load amplitude with Pmax = 18 kN and Pmin = 5 kN. Using the fatigue crack growth data in Problem 5.1, calculate the number of cycles required to grow the crack from a/W = 0.35 to a/W = 0.60. Plot crack size vs. cumulative cycles for this range of a/W.
