Abstract
In this paper, an attempt is made to investigate the effects of the resistance, voltage, capacitance and input energy during the high rate discharge compaction process. The governing differential equation is complicated to solve due to the resistance change during the discharge. An alternative method is presented to solve the equation numerically by substitution of experimentally obtained resistance curves under different circuit conditions. The experimental results reveal that an increase in voltage beyond the breakdown voltage causes a significant increase in current peak as well as number of conducting fibres. Increasing capacitance at constant voltage leads to reduction of instantaneous values of resistance and alteration in cyclic variation of current trace. A high discharge voltage and a minimum level of capacitance are required to obtain full number of longitudinal fibres and avoid molten channel formation, respectively.
