Flexural Strength Testing for Non-Metallics

Three-Point Flexural Test

Flexural testing, also known as bend testing, is a mechanical testing method used to determine the behavior and properties of materials when subjected to bending loads. It involves applying a three-point or four-point bending load to a specimen until it fractures or deforms and measuring the resulting deflection and/or applied load.

Flexural testing is widely used to characterize the mechanical properties of materials such as metals, composites, ceramics, plastics, and concrete. It provides important information about a material's ability to withstand bending loads, its stiffness, strength, and toughness, which are essential for design and engineering applications in aerospace, automotive, construction, and materials science.

Four-Point Flexural Test

In a four point flexural test, the specimen is supported at its two ends and loaded at two points in between. This method is commonly used for materials that are stiffer or when more precise results are required.
