== Introduction == When an object formed of a single material, like a wooden beam or a steel rod, is bent (Fig. 1), it experiences a range of stresses across its depth (Fig. 2). At the edge of the object on the inside of the bend (concave face) the stress will be at its maximum compressive stress value. At the outside of the bend (convex face) the...

Maximum fiber stress developed in a specimen just before it cracks or breaks in a flexure test. Flexural Yield Strength is reported instead of flexural strength for materials that do not crack in the flexure test. An alternate term is modulus of rupture.

Strength of a material in bending, usually expressed in force per unit area, as the stress of a bent test sample at the instant of failure.
