Численное исследование динамической устойчивости вязкоупругих ортотропных прямоугольных пластин с переменной жесткостью

摘要

By numerical simulation the dynamic stability of viscoelasticudorthotropic plates with variable stiffness on the basis of the Kirchhoff-Love hypothesisudin the geometrically nonlinear formulation, taking into account the propagation ofudelastic waves is investigated. The effects of viscoelastic material properties and plateudthickness variation on the dynamic stability are studied.
