Propagation characteristics of shock wave in wire explosive impact forming process

Abstract The theoretical analysis and numerical simulation are combined to explore the generation mechanism propagation characteristics of shock wave in WEIF process. results show that with increase linear density deposition energy, distance same time is longer; as increases, velocity on front gradually decreases. In early stage electric explosion metal wire, shape generated expansion evolution cylindrical wire source,and pressure by close an ellipsoid. Since radioactive, its homogenizes a sphere.
