弯曲 (力学) Bending




弯曲(bending)也称为屈曲(flexure),为材料力学的名词.是指一形状狭长的结构件固体,受到和其长轴垂直的外力时,固体变形的情形。
若结构件在某一方向长度很长,另外二方向的尺寸是该方向尺寸的1/10或更小,即满足上述形状狭长的定义,当其长度显著的大于其宽度及厚度,此结构件会称为梁。

Bending 弯曲 (力学)(重定向自Unsymmetrical Bending)
![]() ![]() ![]() ![]() In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. The structural element is assumed to be such that at least one of its dimensions is a small fraction, typically 1/10 or less, of the other two. When the length is considerably longer than the width and the thickness, the element is called a beam. For example, a closet rod sagging under the weight of clothes on clothes hangers is an example of a beam experiencing bending. On the other hand, a shell is a structure of any geometric form where the length and the width are of the same order of magnitude but the thickness of the structure (known as the 'wall') is considerably smaller. A large diameter, but thin-walled, short tube supported at its ends and loaded laterally is an example of a shell experiencing bending. |
