What is a bending and bending testing machine?
In industrial production and materials research, the bending and bending testing machine is a device widely used to test the bending resistance of materials. It evaluates durability, strength and toughness by simulating the bending forces a material is subjected to in actual use. This article will introduce in detail the definition, working principle, application fields and recent hot topics of bending and bending testing machines.
1. Definition of bending and bending testing machine
A bending and bending testing machine is a device used to test the mechanical properties of materials under bending or bending loads. It applies a certain force or displacement to cause the sample to bend and deform, thereby measuring the flexural strength, elastic modulus, fracture toughness and other parameters of the material. This equipment is widely used in quality control and research and development of metals, plastics, composite materials, paper, textiles and other materials.
2. Working principle of bending and bending testing machine
Bending and bending testing machines usually consist of a loading system, a control system and a data acquisition system. Its working principle is to apply force through a motor or hydraulic system to deform the specimen in three-point bending or four-point bending mode. During the test, the equipment records data such as load, displacement and time, and generates a stress-strain curve to analyze the mechanical properties of the material.
| test mode | Features |
|---|---|
| three point bend | The specimen is supported at both ends and loaded in the middle, suitable for testing brittle materials. |
| four point bend | The specimen is loaded at two points and supported at two points, which is suitable for tough material testing. |
3. Application fields of bending and bending testing machines
Bending and bending testing machines play an important role in multiple industries. The following are its main application areas:
| Industry | Application scenarios |
