Flexural strength test

A material's ability to bend or flex is assessed via flexural testing. It entails positioning a sample between two points or supports and applying a load with a third point or two points, known as 3-Point Bend testing or 4-Point Bend testing, respectively. This procedure is sometimes referred to as a transverse beam test.

On the basis of the incremental load applied, the maximum stress and strain are computed. Results are displayed graphically along with tabular data that includes the yield strength and the flexural strength (for fractured samples) (samples that did not fracture). Plastics, composites, metals, ceramics, and wood are typical materials that are tested.
