Abstract
Wave propagation in sandwich structures with periodic assemblies on elastic foundation under external moving load is studied. Two types of periodic assemblies are considered, namely, a periodic core, and a core with periodically embedded resonators. Wave numbers and traveling wave characteristics are analyzed by introducing a moving coordinate system. Depending on whether the bandgap (attenuation zone) exists, the perturbation due to the external moving load can/cannot propagate through the structure. The bandgap properties of both types of structures in the velocity field are also investigated. It is found that the location and range of the bandgap can be tailored by the physical properties of the core/resonator.
