What is a yield tensile strength testing machine?

The yield tensile strength testing machine is a professional equipment used to measure the yield point and tensile strength of materials during the tensile process. It is widely used in testing the mechanical properties of metals, plastics, rubber, composite materials and other materials, and is an indispensable tool in industrial production and scientific research experiments. This article will introduce in detail the working principle, application fields and related technical parameters of the yield tensile strength testing machine.

1. Working principle of yield tensile strength testing machine

Yield tensile strength testing machines measure the deformation and fracture behavior of materials during stretching by applying increasing amounts of tension. Testing machines usually consist of a loading system, a control system and a measurement system. The loading system is responsible for applying tension, the control system ensures a uniform increase in tension, and the measurement system records the deformation and stress of the material.

During the test, the material will undergo three stages: elastic deformation, plastic deformation and fracture. Yield point refers to the critical point at which a material transitions from elastic deformation to plastic deformation, while tensile strength is the maximum tensile force a material can withstand before breaking.
