| Abstract: | The e-Hopkinson bar test technology is a new dynamic loading technology developed by combining the electromagnetic drive technology with the Hopkinson bar test technology, which replaces the traditional Hopkinson bar with the bullet hitting the loading bar to generate stress waves. In this paper, the application status of e-Hopkinson bar test technology in uniaxial unidirectional/biaxial and dynamic biaxial symmetric compression/tension, interlaminar fracture of composites, dynamic bauschinger effect and other fields are reviewed, including experimental research, theoretical analysis and numerical simulation. Finally, the future development direction of e-Hopkinson bar test technology is prospected. |
