What is a tensile testing machine?
In the fields of industrial production and scientific research, the tensile testing machine is a common testing equipment used to measure the mechanical properties of materials. As hot topics in technology and manufacturing continue to emerge recently, people are paying more and more attention to the strength, durability and other properties of materials. This article will introduce in detail the definition, working principle, application fields of tensile testing machines, and related cases in recent hot topics.
1. Definition of tensile testing machine
A tensile testing machine, also known as a universal material testing machine, is an instrument used to test the performance of materials under the action of external forces such as tension, compression, and bending. It evaluates key parameters such as strength, elastic modulus, elongation at break and other key parameters of the material by applying a controllable force and measuring the deformation of the material.
2. Working principle of tensile testing machine
The working principle of the tensile testing machine mainly includes the following steps:
1.Hold sample: Fix the material to be tested in the upper and lower clamps of the testing machine.
2.Apply force: Apply tensile or compressive force to the sample through a motor or hydraulic system.
3.Measure deformation: Use sensors to record the deformation and force of materials.
4.data analysis: Use software to generate stress-strain curves and calculate the mechanical properties of materials.
3. Application fields of tensile testing machine
Tensile testing machines are widely used in the following fields:
