'Coaxing effect' of prior cycling stress on material fracture mechanics performance
Abstract
The fatigue crack growth rate tests were carried out using aluminum alloy materials served in high-speed train for years, and the relationship of fatigue crack growth rate da/dN and the stress intensity factor ΔK was shown in a broken form in logarithmic coordinates. Compared with the non-service material, the crack growth rate decreases at the initial stage. Aiming at this phenomenon, the aluminum alloy materials were applied here to …
