Alarge (w > > a) plate sample containing an edge (surface) crack with an initial length of 0.010mm is subjected to two sets of uniaxial cyclic (sinusoidal) fatigue loading. the first set of cyclic loading varies between +25 and +125 mpa for 350,000 cycles. the second set of loading varies between +250 and ‐250 mpa. assume the material has a plane strain fracture toughness of 25 mpa m 1/2 and paris law material constants n= 3.1 and c = 1.8x10‐10 for the units given here.
