What is a tensile testing machine?
In industrial production and materials science research, tensile testing machine is a very important equipment used to test the mechanical properties of materials. It measures key parameters such as tensile strength, yield strength, and elongation of materials by applying tensile force. This article will introduce in detail the definition, working principle, application fields and recent hot topics of tensile testing machines.
1. Definition of tensile testing machine
A tensile testing machine, also known as a tensile testing machine, is an instrument used to determine the properties of materials under tensile force. It can accurately measure the stress-strain curve of a material, helping engineers and scientists understand the mechanical behavior of the material.
2. Working principle of tensile testing machine
The working principle of a tensile testing machine is relatively simple: a specimen is held in place by a clamp and gradually increasing amounts of tension are applied until the specimen breaks. During this process, the testing machine records the magnitude of the tensile force and the deformation of the specimen to generate a stress-strain curve.
