What is a tensile testing machine?
In the fields of industrial manufacturing, materials research and quality control, tensile testing machines are an indispensable piece of equipment. It is mainly used to test the tensile, compression, bending, shear and other mechanical properties of materials, and is widely used in metal, plastic, rubber, textiles, composite materials and other industries. This article will introduce in detail the definition, working principle, application fields and recent hot topics of tensile testing machine.
1. Definition of tensile testing machine
A tensile testing machine, also known as a universal material testing machine, is a device that tests the mechanical properties of materials by applying tension or pressure. It can measure key parameters such as tensile strength, yield strength, elongation at break, and elastic modulus of materials, providing a scientific basis for material research and development and quality control.
2. Working principle of tensile testing machine
The tensile testing machine uses a motor or hydraulic system to drive the fixture to apply force to the sample, and at the same time, the force value and displacement are measured through sensors. The data acquisition system transmits force values and displacements to the computer in real time to generate stress-strain curves to analyze the mechanical properties of the material.
