Ultrasonic fatigue tests on a high strength steel for welded structure

摘要：

　　In this paper,the ultrasonic fatigue machine which works at frequency of 20kHz is utilized to conduct the ultrasonic fatigue tests on a high strength welding structural steel with symmetric cycle stress R=-1 at room temperature.Two typical specimen geometries are tested:smooth specimen and notch specimen.The fatigue tests of smooth specimen are also carried out on the electromagnetic resonance equipment at conventional frequency.A comparison is made between the fatigue test results at the ultrasonic and conventional frequency.
