Chapter 1 Design for Flexure - University of Ottawa

Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. The transverse bending test is most frequently employed, in which a specimen having either a circular or rectangular cross … See more When an object is 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 … See more For a rectangular sample under a load in a three-point bending setup (Fig. 3): $${\displaystyle \sigma ={\frac {3FL}{2bd^{2}}}}$$ See more The flexural strength would be the same as the tensile strength if the material were homogeneous. In fact, most materials have small or large … See more • Euler–Bernoulli beam equation • Flexural modulus • Three-point flexural test • Four-point flexural test See more Webdepth. The flexural strength is expressed as Modulus of Rupture (MR) in psi (MPa) and is determined by standard test methods ASTM C 78 (third-point load-ing) or ASTM C 293 (center-point loading). Flexural MR is about 10 to 20 percent of compressive strength depending on the type, size and volume of coarse aggregate used. However, the best ...
