| Flexural modulus | |
Flexural strength is the ability of a material to withstand forces applied perpendicular to its longitudinal axis. The objective of the bending test is to determine the mechanical properties of the materials related to the stresses and arrows (deformations) at the maximum and breaking points, and elastic modulus in bending taking into account the separation between supports calculated from the thickness of the test tube. The bending test is performed on the universal test machine, also used in other tests such as tensile, compression and bending. In this case, it is necessary to change the supports and the loading tool. The test consists of submitting a test piece, resting on the ends, to a force on its perpendicular axis. |  |

The ISO 178 standard investigates the flexural behavior of plastics to determine the flexural strength, the flexural modulus and other aspects of the stress-strain relationship to bending. ASTM D790 describes the proper procedure in detail. Three point and four point bending tools are used to evaluate rigid and semi-rigid materials. The position of the crosshead is not an acceptable measure for the measurement of the deviation when performing a bending test on four |  |
