Material testing machines can perform tests such as tensile, compression, bending, tearing, peeling, and shearing tests, which assess mechanical properties, also known as resistance to deformation.
1. Mechanical properties include strength, elasticity, plasticity, creep, fatigue, and strength.
2. Definition of strength: The ability of a material to resist various deformations and failures under external forces.
3. Strength indicators include yield point, tensile strength, fatigue limit, creep limit, and endurance strength.
4. Tensile test (strength indicators include: spring modulus, specified non-proportional elongation stress, tensile strength, maximum force, etc.).
They can be classified into metallic material testing machines, non-metallic material testing machines, dynamic balancing testing machines, vibration tables, and non-destructive testing machines, etc. Each type of material testing machine differs in its loading method, structural features, force measurement principle, and application range.
