本文采用假定应力分量函数形式的方法,推导出矩形截面梁在二次分布力作用下的艾瑞(Airy)应力函数(多项式),并求解了简支梁和悬臂梁的应力分量。
In this paper, the Airy stress function (polynomial) of rectangular cross-section beam under secondary distribution is deduced by using the method of assumed stress component function, and the stress components of simply supported beam and cantilever beam are solved.
