popup.description2
Using the methods of mechanics, applied mathematics and electrodynamics of continuum, the mathematical models are formulated, analytical, analytical-numerical and numerical and numerical methods are developed in order to determine and study the unsteady and steady-state temperature fields caused by them and components of stress-strain state, given by force factors, in piecewise-homogeneous structure elements, layer and thin-wall including, mainly on the basis of the model of thermosensitive body; thermomechanical behavior of layer bodies is modeled and studied under the action of electromagnetic field or thermal irradiation; mathematical models and methods of investigation the stress-strain state of anisotropic dielectric and pyroelectric with thin inhomogeneities are offered; limit equilibrium of the shells with surface cracks of arbitrary configuration and piecewise-homogeneous limited bodies with cracks is studied under conditions of longitudinal shear. For particular structurally inhomogteneous bodies the influence of external loading, geometric and physical-mechanical characteristics on the parameters of thermal and stress-strain state is analyzed
