1. 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.
2. According to the test time, it can be divided into long-term and short-term test machines.
3. According to the test temperature, it can be divided into high temperature, normal temperature and low temperature test machines.
4. According to the stress state of the sample and the application speed of the test force, it can be divided into static force and dynamic force test machine.
5. According to the method of measuring mechanical properties and testing force application, it can be divided into tensile force, pressure, universal, torsion, creep, long-lasting strength, hardness meter, friction and wear tester, etc.
6. According to the structural principle, it can be divided into mechanical, hydraulic, electronic test machines, etc.
7. According to the process performance test machine, it can be divided into cup protrusion, spring, bending, wire torsion test machine, etc.
2. Tests conducted by the material test function include: tensile, compression, bending, tearing and peeling, shearing and other mechanical properties, also known as mechanical properties, the properties presented by material resistance and deformation.1. Mechanical properties include strength. Elasticity, plasticity, creep, fatigue and strength, etc.
2. Definition of strength: Under the action of external forces, the ability of materials to resist various deformations and damages
3. The strength indicators include yield point, tensile strength, fatigue limit, creep limit, long-lasting strength, etc.
4. Tensile test (strength indicators include: spring modulus, specified non-proportional elongation stress, tensile strength, maximum force, etc.
