Abstract: An electromagnetic induction type Hopkinson pressure/tension bar loading device and experiment method therefor. The device not only can generate compression stress waves but also can generate tension stress waves through the electromagnetic induction principle, and is applied to the loading of a Hopkinson tension bar and a pressure bar. Thus, the loading systems for a Hopkinson tension bar and a pressure bar can simultaneously achieve the strain rate and strain range, which the traditional split Hopkinson bar experiment cannot reach, on the same device, so that the Hopkinson bar experiment technology is standardized, and the experiment devices for a tension bar and a pressure bar are integrated, thereby reducing complexity and floor space of equipment.
