Curved Beam Design

Bending stress is the normal stress induced in the beams due to the applied static load or dynamic load. The study of bending stress in beams will be different for the straight beams and curved beams. In this article, we will discuss the Bending stress in the curved beams. An example of a curved beam would be bending stress in a crane hook. In Straight beam, it is considered that the centroidal axis and the neutral axis coincide. But in curved beams, it is considered that the neutral axis and the centroidal axis do not coincide rather the neutral axis will be shifted towards the centre of curvature. Due to the shifting of the neutral axis towards the centre of curvature, the stress distribution in the curved beam will be non-linear.
