Products Description

3 Points 4 Point Bending Strength Testing is most frequently employed, in which a specimen having either a circular or rectangular cross-section is bent until fracture or yielding using a three point flexural test technique. The flexural strength represents the highest stress experienced within the material at its moment of yield.

The test method for conducting the test usually involves a specified test fixture on a universal testing machine. Details of the test preparation, conditioning, and conduct affect the test results. The sample is placed on two supporting pins a set distance apart.

Purpose of Bending Testing

Bend testing a material allows for the determination of that materials ductility, bend strength, fracture strength and resistance to fracture. These characteristics can be used to determine whether a material will fail under pressure and are especially important in any construction process involving ductile materials loaded with bending forces. If a material begins to fracture or completely fractures during a three or four point bend test it is valid to assume that the material will fail under a similar in any application, which may lead to catastrophic failure. Our 3 Points 4 Point Bending Strength Testing Machine can fully achieve this purpose.

Common Bending Testing Method

There are four common types of bend tests. In a guided bend test, the sample is placed horizontally across two supports and then a force applied to the top of the midpoint deforming the sample into a “U” shape. In a semi-guided bend test, the specimen’s midpoint is bent to a specific angle or inside radius. In a free bend test, the ends of the sample are pushed together, but no force is applied to the bend itself. Finally, a common fracture toughness test (ASTM E399) consists of a sample with a precracked starter crack on the bottom side of the midpoint which is loaded into a 3-point bend fixture so that the midpoint force is applied on the opposite face from the fracture.
