Study of overloading retardation on fatigue crack propagation behavior in 300M steel

Abstract: Based on the fatigue life change of 300M landing gear steel due to overload during service, this study innovatively designed four overload modes according to the actual load spectrum of the landing gear. In this study, the application of overload continued until the specimen failed, and the effects of overload ratio, overload type and specimen thickness on the crack propagation behavior of 300M steel were compared and analyzed. The fatigue crack growth rate and fracture morphology of the specimens were charact… Show more

“…These intermetallic particles resulting from the mentioned alloying elements contribute to matrix reinforcement by impeding the movement of dislocations and promoting grain refinement [7][8][9][10]. The low carbon content in these materials, combined with the low quantity of alloying elements, makes the material easily weldable [11]. However, determining the appropriate welding technique and ideal process still poses challenges for welding engineers [12].…”
