Flexural materials testing is used to characterize the properties of a material loaded in bending.
Depending on the method selected, the two loading conditions are a beam in 3-point or in 4-point bending.
A variety of materials properties are defined by the flexural test methods but the two properties most commonly determined are flexural modulus and flexural strength.
Flexural modulus is a measure of the initial stiffness of the material in bending while flexural strength describes the ultimate stress that the material can support in bending.
Flexural materials properties can be determined at temperatures ranging from -70°C to 200°C.
