挫曲

承受同心轴向负荷的柱出现挫曲的形变
轴向负荷的偏心造成梁元素上的弯矩
不同边界支撑条件下的挫曲情形,四个细长柱材质及形状都相同,但因为不同的边界支撑条件,其挫曲情形不同

挫曲(buckling)也称为屈曲,是一种不稳定的现象,是指细长件在受到压缩力时,因细长件弯曲变形而造成的结构失效

理论上,挫曲是因为力学平衡方程序的解出现分岔(解的本质发生改变)所造成的。在受力增加到一定程度之后,物体会出现二种平衡状态,一种是纯压缩力,另一个是有侧向偏移变形的平衡状态。

挫曲的特点是在结构件中,边缘承受压缩应力的组件突然断裂,而组件失效时的压应力小于材料可以承受的终极抗压应力。挫曲的数学分析一般会设法加入方向也是轴向,但和轴有一段位移(偏心)的压应力,以产生原来理想施力时不会受现的二次弯矩

Buckling 挫曲

A demonstration model illustrating the different
Fig. 3: A one-degree-of-freedom structure exhibiting a tensile (compressive) buckling load as related to the fact that the right end has to move along the circular profile labeled 'Ct' (labelled 'Cc').

In science, buckling is a mathematical instability, leading to a failure mode.

Theoretically, buckling is caused by a bifurcation in the solution to the equations of static equilibrium. At a certain stage under an increasing load, further load is able to be sustained in one of two states of equilibrium: a purely compressed state (with no lateral deviation) or a laterally-deformed state.
