The study’s main aim was to predict the penetrant residual velocity, with it being a vital output parameter in the projectile target interaction. The ballistics have been probed on a wide spectrum of impact velocities for different applications. Determination of the residual velocity by analytical methods entails the use of the impulse momentum principle, and the process is further challenged by the necessary inclusion of various variables that directly affect the calculation of the residual velocity. These problems can be overcome by adopting a non-dimensional approach by determining the combination of variables required for the penetration process by carrying out and validating the non-dimensionalization of the pertinent variables. The process discussed in this study provides a reasonable correlation of the non-dimensional parameters, which was used to estimate and validate penetrant residual velocity. A generalized solution predicting the penetrator residual velocity for a wide range of materials for a variety of impact velocities is proposed. The result of this correlation was validated against the published data, and the method was largely in agreement, showing the robustness of the proposed finding.
