Based on two models of laminated shells, free low frequency vibrations of a three-layered cylindrical panel with the internal layer fabricated of an electrorheological composite are studied. Both models lead to the same governing equations accounting

Pathological changes in the oscillating system of the middle ear can lead to a decrease of the susceptibility threshold of the auditory analyser to sound vibrations and, consequently, to partial or complete hearing loss. Cartilage implants are most o

The paper is concerned with the asymptotically consistent theory of nanoscale plates capturing the spatial nonlocal effects. The three-dimensional (3D) elasticity equations for a thin plate are used as the governing equations. In the general case, th
