And there's a term that's introduced here called the geometric buckling which is analogous to the material buckling that we defined there.

有一个术语要在这介绍，称为几何曲率，那与我们在这定义，的材料曲率是类似的。

The buckling equivalent length of a pile is not only used in the buckling of the pile but also one of the necessary parameter checking the material strength of the pile.

基桩的稳定长度不仅用于基桩的纵向屈曲问题，而且也是桩身材料强度验算必不可少的参数之一。

Based on the first-order shear deformation plate theory, axisymmetric governing buckling equations are derived for a functionally graded material circular plate subjected to in-plane pressure.

基于一阶剪切变形板理论，推导了功能梯度材料圆形板在边界面内均布压力作用下的轴对称屈曲方程。
