Some basic information about the 4-Point Bending Test.
The 4-point bending test is a test method used to evaluate the bending strength and elastic behaviour of a material.
The 4-point bending test is used in particular to determine the mechanical properties of thin plates, plates and similar materials.
The sample is placed in a 4-point support device. This device involves four support points: 2 under the two extremities of the sample and 2 over two points in the middle of the sample.
The test device applies a load to the upper surface of the sample. This load makes the sample bend under the two support points in the middle of the sample. As the load gradually increases, one notes the bending behaviour of the sample.
