摘要：

A new law for high-speed friction is presented in this paper. This law is based on observations made by several investigators regarding the asymptotic behaviour of sliding friction as the speed is increased. The new frictional effect is incorporated into the equations for rigid-body penetration to develop an analytical penetration theory. The new theory is applied to a series of penetration experiments for several steel projectiles into the same concrete target. The results confirm that the new frictional effect is a very promising addition to the theory of rigid-body penetration.
