Abstract : The effect of electromagnetic fields on the stability of cylindrical jets and rods was studied in this research. The goal of the program was to develop a better understanding of the disruptive mechanisms that electromagnetic fields might have on shape charge jets and kinetic energy penetrators. A combined analytical and experimental approach was undertaken. Stability analyses were first performed on perfectly plastic, uniformly elongating jets when subjected to axial electric currents, and later extended to the case of elastic-plastic cylindrical rods. Results from the analyses were verified using a series of small scale, high voltage capacitive discharge experiments.
