We investigate non-linear dynamics of flexible rectangular plates subjected to external shear harmonic load action. We show that an application of the classical and widely used Fourier analysis does not allow to obtain real picture of the frequency v

Nonlinear dynamics of flexible rectangular plates subjected to the action of longitudinal and time periodic load distributed on the plate perimeter is investigated. Applying both the classical Fourier and wavelet analysis we illustrate three differen

A new mathematical model of a porous functionally graded micro/nano-beam under the action of the Casimir force and the Coulomb force is constructed in this paper. The construction of the mathematical model takes into account the Euler-Bernoulli kinem

A theory of flexible shallow nano-shells is developed based on the modified couple stress theory in higher approximation. The shell material is considered as isotropic, elastic and both von Karman and Kirchhoff-Love hypotheses are taken into account.

In this work, a mathematical model of multilayer orthotropic shells with the account of both the 3rd-order generalized model (the so-called Grigoluk-Kulikov model) and a temperature field is presented. An asymptotically stable modified model is propo

The Hamilton - Ostrogradsky principle is used in the paper to construct a mathematical model of vibrations of geometrically nonlinear nano-dimensional shallow axisymmetric spherical shells. The model is based on the following relations and assumption
