N2 - During the launch of electromagnetic railguns, the deformation of high strain rate materials in armature and orbit will affect the orbital launch performance, and it is of great significance to study the instability mechanism of electromagnetic energy materials under high strain rate. This paper presents a novel approach for evaluating the high-speed behavior of metallic materials through the utilization of magnetic pulse drive. The proposed method involves employing the magnetic pressure generated by the magnetic pulse driver (MPD) to apply stress input pulses, enabling uniaxial tensile deformation of the material. To measure the stress-strain relationship of the specimen, the study utilizes high-speed cameras and digital image correlation (DIC) systems. High-speed cameras and digital image (DIC) systems are used to measure the stress-strain relationship of the specimen. At the same time, by establishing a finite element model, it was found that the strain rate can reach 2000 s−1 within a short time and maintain relative stability. Additionally, a tensile experiment was carried out under a charging voltage of 35 kV. The results demonstrated great consistency between the calculation results and the experimental values, which confirming the effectiveness of the proposed method.
