本文讨论无限平面内具有凸缘加劲肋园孔的应力分析问题。所谓凸缘加劲肋系指孔周用型钢或其他形状的构件加劲,进行应力分析时难以将其视为板的一部分来处理的加劲肋。文中讨论了两种荷载情形:一为薄板在无远点处受应力σ_x~(∞)、σ_y~(∞)及τ_(xy)~(∞)的作用;另一为薄板受线性应力的作用。分折方法是:将加劲肋视为园形杆件,把加劲肋与 This article discusses the stress analysis problem of a hole with a flange stiffener in an infinite plane. The so-called flange stiffener refers to the perimeter of steel or other shapes of components of the stiffener, stress analysis is difficult to be regarded as part of the plate to deal with the stiffener. Two kinds of loading cases are discussed in this paper: one is the stress σ_x ~ (∞), σ_y ~ (∞) and τ_ (xy) ~ (∞) of the plate at the far point; the other is the action of the plate by the linear stress . Fractal method is: the stiffener as a circular bar, the stiffener with
