Bending takes place about an axis (called neutral axis), which is perpendicular to the plane of symmetry. It is assumed that beams are made of linearly elastic materials, which …

WebbPure bending refers to flexure of a beam under a constant bending moment. Therefore, pure bending occurs only in regions of a beam where the shear force is zero. In contrast, non uniform bending refers to flexure in the presence of shear forces, which means that the bending moment changes as we move along the axis of the beam. WebbFig. 5.1 Bending of beams. When a beam is subjected to action of any load, then the fibres on one side of the beam are stretched and those on the other side are compressed. If the beam is simply supported, then the lower fibres will be under tension and the upper fibres are on compression. On the other hand, in a cantilever beam the upper ...
