π/2角楔体中的冲击波形成和发展

Generation and Development of Impacting Wave in π/2 Angle Wedge

本文利用弹性动力学中的自相似方法和复变函数论方法,研究了在脉冲匀速运动剪切载荷作用下π/2角楔形弹性体中冲击波的形成和发展。第一次以封闭解的形式给出了应力和位移的表达式,并对高速冲击下的破坏机理进行了解释。

In this paper, generation and development of impacting wave in π/2 angle wedge in case of shear pulse with constant velocity have been investigated by means of the methods of self-similarity and complex function in elastodynamics. Formulae of stress and displacement fields are presented in closed solution firstly, and damage mechanism in high-velocity impacting is discussed.
