Компьютерное исследование динамической устойчивости вязкоупругих прямоугольных пластин с переменной жесткостью

Abstract

By the method of computer simulation the dynamic stability of viscoelastic isotropic plates with variable thickness on the basis of the Kirchhoff-Love hypothesis in the geometrically nonlinear formulation for a weakly-singular Koltunov- Rzhanitsin kernel is investigated. In a wide range of mechanical and geometrical parameters for fast increasing loads the critical load and critical time are determined.
