For a standard case with h = 8 inch and k = 100 psi, the corner deflection is 0.0353 inch under 18-kip single axle load and 0.0459 inch under a 36-kip tandem axle load. If predicted number of load repetition is 5x106, determine the percent erosion damage under single- and tandem-axle load, respectively.
