5.5. Bending of a Simply Supported Narrow Beam

Consideration is now given to the stress distribution in a narrow beam of thickness t and depth 2h subjected to a uniformly distributed loading (Fig. 5.6). The situation as described is one of plane stress, subject to the following boundary conditions, consistent with the origin of an x, y coordinate system located at midspan and mid-height of the beam, as shown:
