What is a tensile testing machine?
In the fields of industrial production, materials research and quality control, tensile testing machines are indispensable equipment. It is mainly used to test mechanical properties such as tensile strength, yield strength, and elongation at break of materials. This article will introduce in detail the definition, working principle, application fields and recent hot topics of tensile testing machines.
1. Basic concepts of tensile testing machine
A tensile testing machine is an instrument used to measure the mechanical properties of materials under tensile force. It records the deformation and fracture process of the material by applying gradually increasing tensile force, thereby obtaining the mechanical property data of the material.
| test items | Description |
|---|---|
| tensile strength | The maximum stress that a material can withstand during stretching |
| Yield strength | The stress value at which the material begins to plastically deform |
| Elongation at break | The elongation of a material at break as a percentage of its original length |
2. Working principle of tensile testing machine
Tensile testing machines usually consist of a loading system, a measurement system and a control system. The loading system applies tension via motors or hydraulics, the measurement system records force and deformation data, and the control system ensures the accuracy and repeatability of the testing process.
| components | Function |
|---|---|
| Load system | apply tension or pressure |
| Measurement system | Record force and deformation data |
| control system | Control the testing process to ensure accuracy |
3. Application fields of tensile testing machine
Tensile testing machines are widely used in multiple industries, including metal materials, plastics, rubber, textiles, composite materials, etc. The following are its main application areas:
| Industry | Application |
