Nonlinear elastic waves in layered bars made of different materials

[摘要] The paper presents experimental observation of strain solitary waves in layered waveguides with layers made of two glassy polymers, PMMA and polystyrene. It is shown that in delaminated structures solitons propagate in each layer independently with parameters typical for waves in each material. In bars with layers bonded with the glassy adhesive a combined wave is formed, propagating as a single one in both layers and exhibiting soliton properties.
