This plane is therefore called the neutral surface of the beam.
因此这个平面称为梁的中性面。

Three variables are considered: critical buckling position, and neutralplane, the fiber buckling half-wavelength.
引入三个变量：临界屈曲位置、中性面位置和纤维屈曲半波长。

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.
