Bend Testing

The mechanical properties of alloys can be evaluated through various tests, one of which is the bend testing. It is a destructive test. In this test, a specimen of the alloy is subjected to an incremental increase in load until it reaches a breaking point. Bend testing can be used to evaluate the flexural strength, strain and stress of an alloy, which is a key factor in determining its suitability for a particular application. The results of bend testing can be affected by a variety of factors, including but not limited to the type of alloy being tested, the thickness of the specimen, and the radius of curvature.

Our Test Projects

Our test projects include, but are not limited to the following.

• Three-Point Bend Test

There are three pressure points in the three-point bend test setup, which are two supports and a centrally loaded test punch. In this test, a supported sample is loaded at the center point and bent to a predetermined angle or until the test sample breaks. This configuration is typically employed in assessing the flexural strength of materials, especially those with low ductility but high stiffness.

If your alloy is to be used in a high strength and stiffness application, such as an aerospace component, then a three-point bend test is usually required. This test helps to determine the material's ability to withstand bending loads without fracturing or undergoing permanent deformation.

• Four-Point Bend Test

In the four-point bend test, the inspection fixture differs from the three-point bend test only in its test punch. A double punch is used instead of a single punch that applies force at the center. In this test, the maximum flexural stress is spread over the section of the beam between loading points. This configuration is usually applied in evaluating the flexural modulus of materials, especially those with high ductility but low stiffness.

If your alloy is to be used in a high ductility and toughness application, such as an automotive component, then a four-point bend test is usually required. This test helps to determine the material's ability to withstand bending loads while undergoing significant deformation.
