Creep buckling of viscoelastic plate considering effect of higher order modes

摘要：

　　This paper reports the creep buckling analysis of viscoelastic rectangular plates under axial compression with initial deflections.A standard linear viscoelastic solid model is used and the von Karman nonlinear geometry equations are introduced in the governing equations.In order to obtain more accurate solution,the deflection function is expressed as a sinusoidal series with four terms rather than only one term.The deformation of viscoelastic plate is gotten numerically.The effect of higher order modes on creep buckling of viscoelastic plate is obtained,the necessity of considering higher order modes is discussed.
