摘要
研究有初始挠度的单向受压粘弹性板的蠕变屈曲问题．在建立控制方程时利用了经典薄板理论．通过求解控制方程得到挠度随时间变化的解析表达式。
The creep buckling of viscoelastic plates with initial deflections,subjected to axial compressive force,was analyzed.The governing equation was developed according to the classical thin plates theory.An analytical solution of deflection varying with time was obtained by solving the governing equation and then instantaneous critical loads and durable critical loads of plates with different length width ratios were got.
