Abstract

A new analytical model for high-speed, velocity-dependent friction was developed and successfully applied to the problem of one-dimensional, hardtarget penetration by a number of high-strength steel, ogive-nosed penetrators [1]. Resulting predictions of penetrator performance and target strength deduced from the model were very consistent and correlated well with previously reported experimental data. Implementation of the mathematical model was subsequently simplified by the development of a stepwise, incremental approximation of the velocity-dependent coefficient of sliding friction [2]. This modification preserved the quality of the linear approximation to the observed velocity dependence in sliding friction
