摘要
讨论了粘塑性靶板中的一维应变波的传播规律。利用广义特征理论导出了应力波传播的特征线和特征关系。利用特征关系和冲击波阵面上的突跃条件,得出了冲击波在传播过程中的演化的规律,并以Bodner-Partom幂函数型粘塑性材料为例。
This paper discusses the propagation of one dimensional strain waves in a viscoplastic slab.The characteristic lines and characteristic relations are derived by using the generalized characteristic theory.By means of the characteristic relations and the jump conditions across a shock wave the evolution rule of the shock is obtained.With the Bodner Partorn viscoplastic materials of power form as example the propagation properties of stress waves in the slab are calculated and discussed.
