Bend Force Testing

Flexural or bending test measures the bending behaviour of beams or beam like samples. Bend testing, sometimes called flexure testing or transverse beam testing, measures the behaviour of materials subjected to simple beam loading. Generally a flexure test is carried out until the sample experiences failure. This test is ideal for testing brittle materials.  

This test is commonly performed on materials such as plastic materials, composites, concrete, and ceramics because these materials have low ductility and hence the propensity to break before any permanent deformation occurs.

This helps in the accurate measurement of the flexural modulus and strength. Bend or flex tests apply force via a single upper anvil at the midpoint, which is a 3-point bend test, or two upper anvils equidistant from the center which would be a 4-point bend test.
