&Nbsp&Nbsp&Nbsp; Test significance and scope of application:

Mechanical performance testing can be applied to any stage of production, from testing the quality of raw materials to checking the durability of finished products.

. Testing can be conducted on a wide range of materials and products, including cosmetics and hygiene products, sports and leisure products, household goods, packaging, toys and novelty items, car interiors, etc. Mechanical performance testing can help companies demonstrate the durability, stability, and safety of their products to customers, thereby gaining a competitive advantage

Main testing items for mechanical properties:

Specific testing significance for major categories: hardness test, Rockwell hardness, Vickers hardness, Micro Vickers hardness, Brinell hardness, Shore hardness, Nano indentation hardness, refers to the "resistance to deformation characteristics of solid materials".

. The local resistance of solids to external object invasion is an indicator of comparing the softness and hardness of various materials. Tensile test, tensile strength, yield strength, elongation after fracture, reduction of area, elastic modulus, Poisson's ratio, tensile strain hardening index, strain hardening tensile test can determine a series of strength and plastic indicators of materials. Strength usually refers to the ability of a material to resist elastic deformation, plastic deformation, and fracture under external forces. Plasticity refers to the ability of metal materials to undergo plastic deformation without failure under load. The commonly used plasticity indicators are elongation and reduction of area. Bending and compression performance Bending strength Bending modulus Compression strength Compression yield point Compression elastic modulus Bending test is mainly used to measure the bending strength of brittle and low plastic materials (such as cast iron, high carbon steel, tool steel, etc.) and reflect the deflection of plastic indicators. Bending tests can also be used to check the surface quality of materials. The maximum compressive load at the time of specimen failure divided by the cross-sectional area of the specimen is called the compressive strength limit or compressive strength. Compression testing is mainly applicable to brittle materials such as cast iron, bearing alloys, and building materials. For plastic materials, the compressive strength limit cannot be measured, but elastic modulus, proportional limit, and yield strength can be measured. Impact toughness test Impact strength Impact toughness Low temperature brittle simply supported beam Impact cantilever beam Impact material's ability to resist impact loads, The practical significance of impact toughness index is to reveal the tendency of materials to become brittle. Fracture toughness test fracture toughness crack opening displacement dynamic fracture toughness measurement crack resistance of components with cracks. Fatigue performance under symmetric stress. Fatigue under asymmetric cyclic stress. Strain fatigue (low cycle fatigue) Fatigue crack propagation rate, thermal fatigue test, corrosion fatigue test, contact fatigue test, high-temperature fatigue test, low-temperature fatigue test, fatigue test, is one of the structural testing contents, which is used to study and verify the fatigue and fracture performance of aircraft structures or components. Fatigue failure is the main form of early failure of mechanical components. The main purpose of fatigue research is to estimate the fatigue life of material structure components to ensure that they do not experience fatigue failure during their service life. High temperature mechanical properties, high temperature creep endurance strength, stress relaxation, high temperature short term tensile test. High temperature components have the ability to resist various deformations and stresses caused by external forces, such as strength, elasticity, plasticity, etc., at high temperatures, Due to the appearance of the liquid phase, the properties, quantity, and distribution state of the liquid phase have a significant impact on the mechanical properties of materials. The wear performance of materials is greatly affected by adhesive wear, abrasive wear, contact wear, and fretting wear. The test method for measuring the wear amount and friction coefficient of materials under given friction conditions is a material test to determine the resistance to wear of materials, and to compare the wear resistance of materials
