Study on the Dynamic Radial Tensile Test Method of Thin-Walled Tube Structure with Special Ring Section

Abstract:

Combined with numerical simulation, a radial-directional dynamic tensile experimental method was proposed based on conventional split Hopkinson tensile bar(SHTB) for a thin-walled tube structure with special ring section. A special clamp was designed and a hollow transmission bar was used to magnify the transmission signals. For the stainless steel thin-walled tube structure, some dynamic tensile experiments are implemented under different strain rates. The results show that this test method is applicable to thin-walled tube structure with special ring section. This structure has a long plastic stage and its fracture strain is reduced with strain rate increasing. Moreover, its tensile strength is obviously enhanced with strain rate increasing
