本文提出了一个新的力学模型,分析了端部受集中质量撞击的悬臂梁的塑性动力响应。为了研究结构的动态失效模式[1],文中重点讨论了剪力的影响以及耗散能在梁中的分配。
In this paper, a new mechanical model is proposed to analyze the plastic dynamic response of the cantilever beam impacted by the lumped mass at the end. In order to study the dynamic failure modes of the structure [1], the influence of shear forces and the distribution of dissipative energy in the beam are discussed.
