Fatigue crack growth behavior and mechanism of aluminum alloy welded joints under overloads

Different parts of high-speed train bogies are usually designed with aluminum alloy materials of varying strengths, and welding is adopted to connect these different parts. When high-speed trains operate under complex road conditions, the bogies will be subjected to tensile overload, which will prod...
