Lattice Vibrations and Superconductivity in Layered Structures

In order to estimate the influence of both surface and interface effects on phonon frequencies and superconducting transition temperatures in layered structures, we have calculated the vibrational modes of structures composed of alternating films of heavy and light particles. An interface effectively lowers the vibrational frequencies of the heavy particles and raises those of the light particl...

Response Spectra of Structures under Subway Induced Vibrations

Passing underground trains induce vibrations transmitted to the ground surface and the nearby structures. Ordinarily, these vibrations do not result in structural damage but can harm nonstructural elements and disturb the occupants. These effects are more pronounced when evaluating buildings like hospitals, laboratories, museums, etc., and their assessment is an important design need. To respon...

Intermodal Resonance of In-plane Free Vibrations of Suspended Cables

The weakly nonlinear in-plane free vibrations of a single suspended cable, or a coupled system of suspended cables, may be classified as gravity modes (no tension variations to leading order) and elasto-gravity modes (tension and vertical displacement equally important). The gravity mode (probably the most common type of vibration of relatively inelastic spans) does not exist for particular val...
