The paper studied the stress wave generation and propagation in a semi-infinite Rayleigh-Love rod due to impact. Three problems have been solved analytically, namely: the stress wave propagations in the rod with prescribed stress or velocity boundary conditions, the stress wave generated in the rod by the impact of an identical rod with finite length, and the stress waves generated by the impact of a rigid solid. Explicit analytical solutions were obtained for these problems. The solutions agree well with numerical simulations. The hyper-viscoelasticity property of a Rayleigh-Love rod is highlighted. The dispersive features of stress wave generation and propagation are exhibited through examples.

Rayleigh-Love 棒中因撞击而产生的应力波

该论文研究了冲击引起的半无限瑞利-洛夫杆中应力波的产生和传播。解析解决了三个问题,即:应力波在规定应力或速度边界条件下在杆中的传播,同一有限长度的同一杆在杆内撞击产生的应力波,以及撞击产生的应力波刚性固体。为这些问题获得了明确的解析解。解与数值模拟非常吻合。突出显示了 Rayleigh-Love 棒的超粘弹性。通过实例展示了应力波产生和传播的色散特征。
