Tensile testing machine is a commonly used material testing equipment, which is mainly used to test the tensile, compression, bending, shearing and other properties of materials. In addition to conventional tension, compression, bending and shear tests, tensile testing machines can also perform some special test items. The following are some common special test items:
1. Fracture toughness test: used to evaluate the tensile ability and plastic deformation ability of materials before fracture, mainly used for the evaluation of metal, plastic, rubber and other materials.
2. Cyclic fatigue test: used to evaluate the durability and life of materials under repeated loading, mainly used for the evaluation of metals, alloys, composite materials and other materials.
3. Rotor dynamic balance test: used to evaluate the dynamic balance performance of rotating parts, mainly used for the evaluation of motors, engines, fan blades and other components.
4. Compression relaxation test: used to evaluate the plastic deformation and relaxation performance of materials under long-term compression, mainly used for the evaluation of foam materials, rubber and other materials.
5. Film tensile test: used to evaluate the tensile properties and breaking strength of film materials, mainly used for the evaluation of plastic films, coating materials, etc.
6. High-speed impact test: used to evaluate the strength and toughness of materials under high-speed impact, mainly used for the evaluation of automotive materials, aerospace materials, bulletproof materials, etc.
7. Thermal expansion test: used to evaluate the expansion performance of materials under temperature changes, mainly used for the evaluation of metals, ceramics and other materials.
These special test items can be realized by changing the configuration and test method of the tensile testing machine. The specific test items need to be determined according to the characteristics of the material and the test requirements.
