A Simplified Approach for the Determination of Penetrant Residual Velocity for Penetration Processes

摘要

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