Typical lectromechanical Universal Testing Machine Test fixture for three point flex test. A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing ...
Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength , breaking strength , maximum elongation and reduction in area. [ 2 ]
The four-point 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 very similar to the three-point bending flexural test. The major difference being that with the addition of a fourth bearing the portion of the beam between ...
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 preparation and testing.
A laser extensometer is an extensometer capable of performing strain or elongation measurements on certain materials when they are subjected to loading in a tensile testing machine. The principle works by illuminating the specimen surface with a laser , the reflections from the specimen surface are then received by a CCD camera and processed by ...
In materials science and solid mechanics, biaxial tensile testing is a versatile technique to address the mechanical characterization of planar materials.It is a generalized form of tensile testing in which the material sample is simultaneously stressed along two perpendicular axes.

During the testing for determination of the loads, no fracture must occur at the ultimate load for a period of 3 seconds. This is also commonly used in knowing the properties of metal beams. For example, it is used in experiments such as T.T.M. (tensile testing machine) and U.T.M. (universal testing machine)
