Universal testing machine is a device widely used to test the mechanical properties of various materials. It can be used to test the tensile, compression, bending, shearing, tearing and other mechanical properties of metals, plastics, rubber, paper, textiles and other materials. The use of universal testing machine can help production and research units to determine the strength, hardness, durability, ductility and other performance parameters of the material, and provide a scientific basis for the production and application of the material.

The use of universal testing machine is mainly divided into the following aspects:

Material strength test:

The universal testing machine can be used to test the tensile, compressive, bending, shearing and other strength indicators of various materials. When testing, the sample is clamped in the fixture of the testing machine, the corresponding load is applied, and the change curve of load and displacement is recorded, from which the strength index of the sample can be calculated.

Material durability test:

The universal testing machine can be used to test the durability of materials, such as fatigue life, cycle strength and other indicators. During the test, the sample is clamped in the fixture of the testing machine, cyclic loading is carried out according to the set load and displacement curve, and the strain and load changes of the sample are recorded, from which the durability index of the sample can be calculated.

Material hardness test:

Universal testing machine can be used to test the hardness of materials, such as Brinell hardness, Vickers hardness and so on. When testing, the hardness tester is installed on the test machine, the sample is sandwiched-in the fixture of the hardness tester, the load is applied according to the specified method, and the indentation depth of the sample is recorded, from which the hardness index of the sample can be calculated.

Material ductility test:

The universal testing machine can be used to test the ductility index of the material, such as elongation, elongation at break, etc. When testing, the sample is clamped in the fixture of the testing machine, the corresponding load is applied, and the change curve of load and displacement is recorded, from which the ductility index of the sample can be calculated.

Material dynamic test:

Universal testing machine can be used to test the dynamic properties of materials, such as impact toughness, dynamic strength and other indicators. When testing, the sample is clamped in the fixture of the testing machine, the impact load is tested according to the set impact speed, and the strain and load changes of the sample are recorded, from which the dynamic performance index of the sample can be calculated.

In addition to the above common uses, the universal testing machine can also be used for some other tests, such as bonding performance test, friction performance test, tensile fatigue test, etc. The use of universal testing machines for these tests requires the selection of different fixtures and loading modes according to different test requirements.
