What is a metal tensile testing machine?
The metal tensile testing machine is a professional equipment used to test the mechanical properties of metal materials. It is widely used in industrial manufacturing, scientific research experiments, quality inspection and other fields. It measures key parameters such as strength, ductility, and elastic modulus of materials by applying forces such as tension, compression, and bending to provide a scientific basis for material performance evaluation. The following is a detailed introduction to the metal tensile testing machine.
1. Working principle of metal tensile testing machine
The metal tensile testing machine applies tension to the specimen through a hydraulic or electric drive system, while recording force and displacement data in real time through sensors and control systems. The test results can be used to analyze the tensile strength, yield strength, elongation at break and other indicators of the material.
| test items | definition | Application scenarios |
|---|---|---|
| tensile strength | The maximum tensile force a material can withstand before breaking | Metal plate and wire quality inspection |
| Yield strength | The stress value at which the material begins to plastically deform | Structural component design verification |
| Elongation at break | The ratio of the elongation of a material at break to its original length | Evaluate material toughness |
