Mechanical properties:
The mechanical properties of materials refer to the mechanical characteristics of materials under various external loads (tensile, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium and humidity).
Test significance and application scope:
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. The test can be carried out on a wide range of materials and products, including cosmetics and sanitary products, sports and leisure products, household products, packaging, toys and novelty goods, automobile interior decoration, etc. Mechanical performance testing can help enterprises prove to customers the durability, stability and safety of their products, thus gaining competitive advantage.
Contents of mechanical performance test:
Hardness test: Rockwell hardness, Vickers hardness, micro Vickers hardness, Brinell hardness, shore hardness, nano indentation hardness, etc.
Tensile test: tensile strength, yield strength, elongation after fracture, section shrinkage, elastic modulus, Poisson ratio, tensile strain hardening index, strain hardening, etc.
Bending and compression performance test: bending strength, compression strength, compression yield point, compression modulus of elasticity, etc.
Impact toughness test: impact strength, impact toughness, low temperature brittleness, simple beam impact, cantilever beam impact, etc.
Fracture toughness test: dynamic fracture toughness, crack opening displacement, fracture toughness, etc.
Fatigue test: low temperature fatigue, high temperature fatigue, contact fatigue, corrosion fatigue, thermal fatigue, strain fatigue, etc.
High temperature mechanical properties test: creep, stress relaxation, durability, etc.
Wear performance test: contact wear, fretting wear, adhesive wear, abrasive wear, etc.
Peel strength test: peel strength of tape, etc.
