When a curved beam is bending in the plane of the curvature, the neutral axis of cross section is not identical with the axis of gravity due to the influence of the initial curvature.
由于曲率的影响，曲线梁在其曲率平面内弯曲时的中性轴不通过横截面的形心。因此弯矩在形心处要引起正应力，从而引出所谓“等效轴力”的概念。
Elementary Elastic bending theory requires that bending stress varies linearly with distance from the neutral axis, but plastic bending shows a more accurate and complex stress distribution.
基本弹性弯曲理论要求弯曲应力均随到中性轴的距离而线性变化，但塑性弯曲理论揭示了一个更加精确的和复杂的应力分布。
