摘　　要：分析和研究了强冲击下线弹性体中与质点非线性运动有关的运动非线性效应。研究结果表明，运动非线性的动态响应十分显著，在分析和计算中不可忽视。本文还研究了线弹性体中运动非线性波的激波构成和传播。Kinematic nonlinearities concerned with nonlinear motion of material particles are investigated in this paper.It is found that the effects of the kinematic nonlinearity are significant when a body is subjected to extremely heavy impact,even if the material is assumed to be linearly elastic.The nonlinear esponse is nonnegligible.Shock formation and propagation of kinematically nonlinear waves in linearly elastic bodies are studied as well.
