What is a bending tensile testing machine?
In industrial production and materials research, the bending tensile testing machine is a very important equipment used to test the bending properties and tensile strength of materials. This article will introduce in detail the definition, working principle, application fields and recent hot topics of the bending tensile testing machine.
1. Definition of bending tensile testing machine
A bending tensile testing machine is a device used to test the mechanical properties of materials under bending and tensile loads. It measures the bending strength, elastic modulus, fracture toughness and other parameters of materials by applying controllable force, and is widely used in metals, plastics, composite materials and other fields.
2. Working principle of bending tensile testing machine
The working principle of the bending tensile testing machine is to apply force through a mechanical or hydraulic system to cause bending or tensile deformation of the sample. At the same time, the force and displacement are measured through sensors to calculate the mechanical properties of the material. Here is a brief description of its workflow:
| steps | Description |
|---|---|
| 1. Sample preparation | Cut the material into standard size samples, making sure the surface is smooth and free of defects. |
| 2. Install the sample | Fix the sample on the fixture of the testing machine to ensure uniform force. |
| 3. Apply load | Increasing forces are applied through the control system and force and displacement data are recorded. |
| 4. Data analysis | Calculate the bending strength, elastic modulus and other parameters of the material based on the measured data. |
3. Application fields of bending tensile testing machine
Bending tensile testing machines play an important role in multiple industries. The following are its main application areas:
| Industry | Application |
|---|---|
| metal material | Test the bending properties and tensile strength of metal plates and bars. |
| plastic industry | Evaluate the toughness and bending resistance of plastic products. |
| composite materials | Study the interlaminar bond strength and bending properties of composite materials. |
| building materials | Test the mechanical properties of construction materials such as concrete and steel bars. |
4. Recent hot topics
Recently, hot topics about bending tensile testing machines mainly focus on the following aspects:
