Численное исследование динамической устойчивости вязкоупругих ортотропных прямоугольных пластин с переменной жесткостью

Abstract

By numerical simulation the dynamic stability of viscoelastic orthotropic plates with variable stiffness on the basis of the Kirchhoff-Love hypothesis in the geometrically nonlinear formulation, taking into account the propagation of elastic waves is investigated. The effects of viscoelastic material properties and plate thickness variation on the dynamic stability are studied.
