The bending normal stress amplitudes of the nodes in the critical section near crankshaft fillet were obtained by modal expanded computation.
最后通过模态扩展计算得到圆角危险截面圆弧上各点在疲劳试验过程中的弯曲正应力幅值。
Therefore, the bending moment may cause normal stress at the axis of gravity, and the concept of "equivalent axial force" is induced.
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。
For rail anti-slide piles, the bending moment, normal stress and anti-slide force of rail anti-slide pile are calculated inversely based on flexure deformation measured by inclinometer.
对于钢轨抗滑桩，把测斜仪所测横向变形当作钢轨桩的弯曲变形，然后再反算出钢轨桩的弯矩、正应力和抗滑力。
