Abstract : This report presents analytical solutions for the velocity and position of necks in a rod stretching under large velocity gradients. Solutions are based on assuming various forms for the yield strength of the rod. The model predicts many phenomena seen in stretching shaped charge jets without recourse to probalistic perturbations.
