摘要
应力波传播理论是分析结构和材料在爆炸/冲击载荷作用下的响应及破坏特性的基础,在国防和民用工程上有重大价值.论文对作者们近半个世纪来在非线性应力波传播理论的发展及其工程应用方面所开展的主要研究作一回顾和讨论,包括:几类非线性应力波相互作用及失效,非线性粘弹性波传播理论及应用,动态破坏和应力波相互作用,以及应力波理论在防护工程中的应用等.
Stress wave propagation theory is the basis for analyzing the dynamic response and failure characteristics of structures and materials under explosion/impact loads. It is of significant value in the de- fense and civil engineering. A review and some discussions on the development of the theory of nonlinear stress wave propagation and its engineering applications,carried out by the authors in nearly half a centu- ry,are presented in this paper,which includes the interaction of nonlinear stress waves and unloading fail- ure due to the unloading stress wave, the theory of nonlinear viscoelastic wave propagation and its application,the interaction between dynamic damage/failure and stress wave, as well as the application of stress wave theory in protective engineering.
