A bending test has a merit that detection of deformation is relatively easy and a demerit that a stress state is not simple as compared with a compression or tension test.
弯曲试验有着能比较容易地探测变形的优点，缺点是应力状态不象压缩或拉伸试验那样简单。
Based on the analytical formula of the plane stress state, a simple and direct distinguishing method is derived with regard to the direction in which the maximal extremes lie.
本文根据平面应力状态的解析式，推导出了一种判别最大应力极值所在方向的简捷方法。
