【Abstract】 The tensile and compress fatigue function of material test machine of Instron 1251 was used in the research. Under high frequency, The dynamic property of a material can be got by tensile load. The dynamic tensile test on material test machine of Instron 1251 can meet the demand of studying the mechanical behaviour of metals and nonmetals in high strain rate.更多还原
