原始语种摘要: Abstract(#br)As an extension of the Taylor model, in 2001 Lu et al. [13] made a study on the impact behavior of a flat-nosed cylindrical porous projectile in order to determine the dynamic yield stress of porous materials at a high strain rate. They assumed that the density of the compressed porous material was a linear function of the compressive strain, which was only suitable for small strain cases. In 2010, as another extension of the Taylor model, Yang et al. [16] proposed a theoretical model to study the flat-nosed solid cylindrical projectile impinging against a semi-infinite elastic bar along its axial direction, which provided a useful guide for the application of the output bar in a Hopkinson test system to obtain instantaneous deformation characteristics of the projectile....
