矩形截面梁受多项式分布载荷的应力解

本文根据弹性力学半逆解法，对矩形截面梁的主要边界上受高次多项式分布力，提出一个统一的应力函数模式，运用此应力函数可以求解矩形截面梁受５次以内多项式分布载荷时的应力分量．文章以矩形截面梁受５次分布截荷为例，给出了材料力学弯曲正应力公式的修正项．

The solution for Stress In the Beam of Rectanglar Section Subjected to Polynomial Distributed load

This paper according elastic mechanics semi-inverse method the function form of stress for beam of rectangular section subjected to Polynomial distributed load on major boucndary is propsed The stresses are solved for the beam subjected to polynomial distribubed load within fifth order The revision of bending stress for strength of materials is shown in an example.
