| 摘 要： | 研究了有初始小挠度单向受压粘弹性板在两种民政部下的蠕变屈曲问题。第一种情况是建立控制方程时忽略横向剪切变形；第二种情况是不忽略横向剪切变形。通过求解控制方程得到了挠度随时间扩的解析表达式，从而又得到了瞬时临界载荷和持久临界载荷，并讨论了横向剪切变形对临界载荷的影响。

| Abstract: | The creep buckling of viscoelastic plates with initial deflections,subjected to axial compressive force is analyzed in the following cases:first,transverse shearing deformation is ignored,second,transverse shearing deformation is considered.An analytical solution of instantaneous and durable critical loads is obtained by solving the governing equations.The effect of transverse shearing deformation on the critical loads is also discussed. |

| Keywords: | thin plates critical load creep buckling transverse shear deformation |
