This study investigates stress wave generation and propagation in a semi-infinite Rayleigh-Love rod due to impact using analytical methods. Three specific problems were solved and explicit analytical solutions were obtained which agree well with numerical simulations. The hyper-viscoelasticity property of a Rayleigh-Love rod is highlighted and dispersive features of stress wave generation and propagation are demonstrated through examples.
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.
