摘要

摘要研究了几何非线性和材料非线性对受旋转分布载荷作用的绕中轴对称截面悬臂梁的综合影响。假定压缩时的应力应变关系与拉伸时的应力应变关系相同。因此，中性轴与光束的中心轴重合。该问题是用一个积分方程来表示的，该积分方程适当地转化为一个非线性常微分方程组，用简单而精确的数值方法来求解。详细介绍了工字梁和矩形截面梁的荷载挠度特性。

Large deflection analysis of cantilever beams of symmetrical cross-section subjected to a rotational distributed loading including the effect of material nonlinearity

Abstract Combined effects of geometrical and material non-linearities on a cantilever beam having symmetrical cross-section about its central axis with a rotational distributed loading are studied. It is assumed that the stress-strain relation in compression is identical to that in tension. Due to this, the neutral axis coincides with the central axis of the beam. The problem is formulated by means of an integral equation which is suitably converted to a system of nonlinear ordinary differential equations which are solved using a simple and accurate numerical method. Details of the load deflection characteristics for an I-beam and for a beam of rectangular cross-section are presented.
