STRIATIONS IN EWP.
Abstract
Striations in exploding wires have been examined in sequential frame studies to investigate the possibility that gas discharge type striations are formed in the electron-vapor sheath. These electrical striations, due to localized space charge formed by impact, move in the direction of majority electric current carrier motion. Explosions were carried out on samples immersed in distilled water in order to impede outgassing which could mask striations. No. 28 copper wire samples in 1 and 2 cm lengths were connected across a 45 microfarad capacitor bank charged to 3 to 8 kV. Within the range of electric fields used in this experiment, no movement of striations were observed. Comparison of striations in annealed and unannealed wires show that it is not likely that low velocity striations are present. The existence of mechanical striations has been firmly established.
