摘要
为了了解筒仓洞口在弯矩作用下的应力分布,利用平板理论结合复变函数和保角映射技术,研究了筒仓开孔的孔口应力集中问题,通过将仓壁孔口的应力计算简化成平面问题,求出了孔口的应力,得出在平面外弯矩作用下,弯曲应力集中主要发生在和弯矩作用方向垂直的边.
In order to understand stress distribution of silo wall opening under moment, using plate theory, complex variable function and conformal mapping technique, the problem of orifice stress concentration in silo opening is studied through silo wall opening is simplified as plane problem in stress calculation, and then, the stress concentration of opening is obtained. Moreover, when it is subjected to out-plane moment, bending stress concentration mainly exists in perpendicular side of bending direction.
