What is simple bending?

Simple beam bending is often analyzed with the Euler–Bernoulli beam equation. The conditions for using simple bending theory are: The beam is subject to pure bending. This means that the shear force is zero, and that no torsional or axial loads are present. The material is isotropic (or orthotropic) and homogeneous.

What do you mean by bending stress?

Bending stress is a more specific type of normal stress. When a beam experiences load like that shown in figure one the top fibers of the beam undergo a normal compressive stress. The stress at the horizontal plane of the neutral is zero. The bottom fibers of the beam undergo a normal tensile stress.
