Determination of Steady-State Amplitudes in the Region of Dynamic Instability of a Viscoelastic Plate

摘要

The problem of determining the amplitude of oscillations in the region of dynamic instability of a rectangular plate,the material of which obeys the hereditary law of deformation,in a geometrically nonlinear formulation is considered.The differential equation of plate oscillations under the action of constant and variable loads in its plane was obtained.It has been found also the amplitude of steady-state oscillations and was drawn amplitude-frequency curve.
