Creep buckling analysis of viscoelastic plates considering geometric nonlinearing

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 an accurate solution, the deflection function is expressed as a sinusoidal series with four terms.
