What is a material tensile testing machine?
In the fields of industrial manufacturing, materials science and product quality control, material tensile testing machines are an indispensable piece of equipment. It is used to test the mechanical properties of materials, such as tensile strength, elongation, elastic modulus, etc. This article will introduce in detail the definition, working principle, application scenarios and recent hot topics related to the material tensile testing machine.
1. Definition of material tensile testing machine
A material tensile testing machine, also known as a universal material testing machine, is a device that tests the mechanical properties of materials by applying forces such as tension, compression, bending or shearing. It can accurately measure the deformation and fracture behavior of materials during stress, providing important data for material development and quality control.
2. Working principle
The working principle of the material tensile testing machine is to drive the fixture through a motor or hydraulic system to apply gradually increasing force to the sample, while recording force and deformation data through sensors. This data is transferred to a computer system for analysis, producing results such as stress-strain curves.
