Because these materials have a very low ductility they will break before any permanent deformation of the sample occurs allowing for the accurate measurement of the flexural modulus and strength. The most common materials tested in flexure are plastic materials, composites, concrete, and ceramics. Generally, a flexure test is run until the sample experiences failure and is therefore ideal for the testing of brittle materials. What Are the Different Types of Flexure Testing Materials? Bend tests are used with ductile materials whereas flexural tests are used with brittle materials. The three point flexure test is ideal for the testing of a specific location of the sample, whereas, the four point flexure test is more suited towards the testing of a large section of the sample, which highlights the defects of the sample better than a 3-point bending test.Ī bend test is similar to a flexure test in the type of hardware and test procedure involved. A four point bend test is roughly the same except that instead of the force applied through a single point on top it is applied through two points so that the sample experiences contact at four different points and is bent more in the shape of a “U”. A three point bend test consists of the sample placed horizontally upon two points and the force applied to the top of the sample through a single point so that the sample is bent in the shape of a “V”. The two most common types of flexure test are three point and four point flexure bending tests. Shop Flexural (Bend) Test Machines What Are the Different Flexure Test Types? When a specimen is placed under flexural loading all three fundamental stresses are present: tensile, compressive and shear and so the flexural properties of a specimen are the result of the combined effect of all three stresses as well as (though to a lesser extent) the geometry of the specimen and the rate the load is applied. Unlike a compression test or tensile test, a flexure test does not measure fundamental material properties. These two values can be used to evaluate the sample materials ability to withstand flexure or bending forces. Flexural modulus is calculated from the slope of the stress vs. Flexural strength is defined as the maximum stress at the outermost fiber on either the compression or tension side of the specimen. The most common purpose of a flexure test is to measure flexural strength and flexural modulus. The maximum recorded force is the flexural strength of that particular sample. The material is laid horizontally over two points of contact (lower support span) and then a force is applied to the top of the material through either one or two points of contact (upper loading span) until the sample fails. A flexure test is more affordable than a tensile test and test results are slightly different. Flexure (Bend) tests are generally used to determine the flexural modulus or flexural strength of a material.
