Abstract

Using the dynamic explicit program NET3D, oblique impact between long rod penetrator and metallic plate was analyzed. Compared with an experiment and AUTODYN-3D analysis result, the accuracy of NET3D program was examined. It was proved that NET3D program could analyze comparatively exactly oblique impact phenomenon between long rod penetrator and metallic plate. The final deformed configuration of penetrator predicted by NET3D program was more close to experimental result than commercial program AUTODYN-3D. But, in order to increase the reliability of NET3D program in the simulation of tensile fracture phenomenon, the additional research is required.
