The three-point bending flexural test provides values for the modulus of elasticity in bending , flexural stress , flexural strain and the flexural stress–strain response of the material. This test is performed on a universal testing machine (tensile testing machine or tensile tester) with a three-point or four-point bend fixture. The main advantage of a three-point flexural test is the ease of the specimen .

The 3-point bending test bears this name because there are three pressure points in this test setup: Two supports and a centrally loaded test punch. The specimen lies crosswise on the supports and protrudes at the sides. The 3-point bending test is .While it is easy to imagine why bend testing needs to be performed on rigid materials like plastics (ASTM D790) and concrete (ASTM C1609), in reality bend test applications are common in a variety of industries. Universal testing machines equipped with bend fixtures are used to calculate flexural modulus, flexural strength, yield point, and more. For this reason, the four-point flexural test was developed. The single loading pin is just substituted by a double pin. Between these points there is a shear force-free range with a constant bending moment. Figure: Distribution of bending moment and shear force in 3- and 4-point flexural tests Determination of the Young’s modulus Universal testing machines equipped with bend fixtures are used to calculate flexural modulus, flexural strength, yield point, and more. . Three-point bend fixtures: Configuration of flexural .
The ideal 3 point bending test machine for a high velocity flexural test is an instrumented drop weight impact testing machine equipped with a 3 point bend fixture and an insert of a given shape attached to the tup. During the impact, the load is recorded by the sensor (piezoelectric or strain-gauge) embedded in the tup. .Universal testing machine load frames come in single or dual column configurations and are available in force capacities up to 2,000 kN. . When a 3-point bend test is done on a brittle material like ceramic or concrete, flexural strength is often called modulus of rupture (MOR).Universal testing machine load frames come in single or dual column configurations and are available in force capacities up to 2,000 kN. . When a 3-point bend test is done on a brittle material like ceramic or concrete, flexural strength is often called modulus of rupture (MOR).This test setup includes a 3400 Series test system with a 3-point bend fixture and no extensometer, meaning that strain in this case must be measured by crosshead displacement (Type 1 testing). Whenever strain is measured via crosshead displacement, compliance correction is recommended, though not required. 3400 series test frames can also be .
The test uses a universal testing machine and a three point bend fixture to bend plastic test bars to acquire the data needed to make the calculations. The calculations and set-up for D790 are more complex and time consuming compared to other tests so please read the entire specification from ASTM before running the test. ISO-180 is similar in .Fig.1(a) shows a guided bend test jig that uses a male and a female former, the commonest form of equipment Fig.1(b) shows a wrap-around guided bend test machine that works on the same principles as a plumber's pipe bender. The .

The specimen used for the three-point bending test is a beam similar to the one sketched in Figure 3. . mode where the computer software can be used to run the machine. 3.2 Fixtures, specimen positioning and CMOD installation Put the machine in standby mode via rotating the switch denoted by #4 (in Figure 1) to its leftmost . Bend tests are usually carried out on a universal testing machine (UTM) using a 3 or 4-point bend fixture. The bend test uses a test specimen that is bent in three-point bending to a specified angle. In the Guided bend test the test specimen is wrapped around a former of a given diameter as per the test specification.The ideal 3 point bending test machine for a high velocity flexural test is an instrumented drop weight impact testing machine equipped with a 3 point bend fixture and an insert of a given shape attached to the tup. During the impact, the load is recorded by the sensor (piezoelectric or strain-gauge) embedded in the tup. .Our bend test machine will measure strength, bending modulus of elasticity, elongation, ductility and toughness. . The test is the same as a 3-Point bend test and is called transverse because it's perpendicular to the beam's length. Measurements include flexural strength (or bend strength, modulus of rupture,and transverse rupture strength .

An MTS application engineer demonstrates a 3-point bend test. Watch the Video Video . Faster Data Acquisition When Testing Composites .Flexural testing is used to determine the flex or bending properties of a material. Sometimes referred to as a transverse beam test, it involves placing a sample between two points or supports and initiating a load using a third point or with two points which are respectively call 3-Point Bend and 4-Point Bend testing.
The main equipment used in a bend test is a universal testing machine or a specific bend testing machine. Other equipment includes the necessary supports and anvils. Why use a 4 point bend test? The 4-point bend test is used as it provides a constant moment region in the material, and it can provide more accurate measurements of the material .You are now ready to perform a 3-Point Bend Test.
