Effect of periodic overloads in particle reinforced aluminum alloys: the near threshold behavior


The influence of periodic overloads on the fatigue crack propagation behavior in the near threshold regime of physically (extrinsically) short cracks and long cracks is investigated. The overload ratio and the number of base amplitudes were 1.8 and 1000 cycles, respectively. A 20 vol.% SiC particle reinforced 359 cast aluminum alloy and a 17 vol.% SiC… (More)
