| 摘 要： | 根据弹性力学全逆解法,对矩形截面梁的主要边界上受三次多项式分布压力,提出了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任意三次多项式分布载荷时的应力分量。该方法简单、实用,克服了选择应力函数的盲目性,在实际中有广泛的实用价值。

| Abstract: | This paper introduces elastic mechanics inverse method.The function form of stress for beam of rectangular section subjected to polynomial distributed load with third order on major boundary is proposed.The stresses are solved for the arbitrary beam subjected to polynomial distributed load within third order.This simple and practical method can conquer the blindness of selecting stress function and has wide practical value in reality. |
