What is a tensile testing machine?
In industrial production and material science research, the tensile testing machine is a very important equipment used to test the tensile properties of materials. With the advancement of science and technology and the increase in industrial demand, the application of tensile testing machines is becoming more and more widespread. This article will introduce in detail the definition, working principle, application fields and popular models of the tensile testing machine.
1. Definition of tensile testing machine
Tensile testing machine, also known as tensile testing machine or universal material testing machine, is a device used to measure the mechanical properties of materials in tension, compression, bending and other tests. It applies force and measures the deformation of the material to calculate key parameters such as the material's tensile strength, yield strength, and elongation at break.
2. Working principle of tensile testing machine
The working principle of the tensile testing machine is based on the cooperative work of mechanical sensors and displacement sensors. Here is its basic workflow:
| steps | Description |
|---|---|
| 1 | Fix the specimen in the upper and lower clamps of the testing machine |
| 2 | Start the testing machine and apply tensile force |
| 3 | Sensors measure force and displacement in real time |
| 4 | Software system records data and generates stress-strain curves |
| 5 | Analyze the data to obtain the mechanical property parameters of the material |
3. Application fields of tensile testing machine
Tensile testing machines are widely used in many industries. The following are its main application areas:
| Industry | Application |
