Frequently Asked Questions about Material Testing Machines

1. Tests performed in material testing functions include: tensile, compression, bending, tearing, peeling, shearing, etc.
Mechanical properties are also called mechanical properties, properties presented by material resistance and deformation;
1. Mechanical properties include strength, elasticity, plasticity, creep, fatigue and hardness.
2. Strength definition: the ability of the material to resist various deformations and damage under the action of external forces;
3. Strength indicators include yield point, tensile strength, fatigue limit, creep limit, long-lasting strength, etc.
4. Tensile test (strength) indicators include: elastic modulus, specified non-proportional elongation stress, tensile strength, force, elongation, fracture strength, elongation, etc.

2. Material testing machine: It is an instrument and equipment that tests mechanical properties and process performance of materials, parts and components, also known as a mechanical performance testing machine.
1. According to the object, it can be divided into metal and non-metallic material testing machines;
