The study of material properties began in the European Industrial Revolution, when mechanical testing equipment was used to conduct static tests to evaluate the mechanical properties of materials under tensile and bending loads. In recent years, alloy materials, polymer materials, ceramic materials, superconducting materials such as the development and use of new materials, has greatly expanded the tensile testing machine applications.

Rubber Rally with the functions are:

1, the rubber tensile testing machine must be able to accurately describe the stress-strain curve of the installation. There is an intimate connection between the tension value in the tensile specimen and the gauge length.

2, Tensile testing machine must be precise gauge measurement and documented installation. Specimen gauge measurement is the main data to calculate the elongation of the rubber, so the tensile test machine rubber tensile test machine must accurately measure the strain of the sample, and immediately recorded down.

3, high-precision and high-frequency data acquisition. Stretch rubber does not require a lot of force, tension measurement is not very large, so the demand value of the higher precision. General requirements of the test machine can be obtained after more than two decimal precision point of force. In addition, because the tensile testing machine to detect the tensile properties of the rubber tensile process requires a number of tension values, and tensile experiments and not repeated, so real-time accurate records of each experimental section of the pull force values on the experimental success plays a very important effect .

4, the need to test the rubber pulling machine stroke Because the rubber in the deformation of a large amount of tension, especially latex products, the elongation can be as high as 1000% or more. It is necessary to ensure that the gripper has sufficient stroke before the rubber specimen is broken.

At present, the tensile testing machine mainly for the strength, stiffness, hardness, elasticity, ductility, ductility, ductility, surface and internal defects and other mechanical properties of the test and analysis, can be widely in the mining enterprises, measurement departments, Machinery, petrochemicals, food, pharmaceutical packaging, vehicle manufacturing, wire and cable, textile fibers, plastics and rubber, building materials and other industries and trades. The field of laboratory and laboratory, the specific areas related to aerospace, machinery manufacturing,

From the perspective of mechanical experiments, tensile testing machine application areas can be divided into two parts: First, structural mechanics, one experimental mechanics (including materials research and material testing). In the past, tensile testing machine commonly used in automotive parts, plastics, rock mechanics, engineering structures and other traditional areas of conventional materials testing. In recent years, with China's rapid economic development, people need lighter and stronger materials for the manufacture of aircraft, rockets, cars, which makes the application of tensile testing machine gradually to a more detailed areas, newer direction. From large aircraft, missiles, rockets, satellites and other large structures, small to human bones, eye sclera, electronic materials, glass, beef jerky, cloth, etc., can be described and our clothing, food, shelter,

In addition, with the extensive use of tensile testing machine, material testing personnel engaged in the performance of the material has become quite large. In the case of professional conferences, many large-scale mechanics conferences, such as the International Conference on Fracture Mechanics, Fatigue and Fracture Conference, and Conventional Mechanics Conference, are held every year at home and abroad.
