A simple tensile test determines only one set of properties of a material, at a specific temperature, and a specific strain rate. The placing of the material in tension identifies the Young's Modulus of the material: the amount of stretch in the material for a specific amount of applied stress. As the material is pulled, the response becomes non linear (In metals and plastics), and the Yield Strength of the material is identified. As the test continues, the material finally fractures at what is called the Ultimate Tensile Strength. Associated with these strengths are the deformations of the material.
The disadvantages of the test are many.
1. It does not provide information about the material at different temperatures.
2. It does not identify the strength of the material at differing strain rates.
3. It does not identify any possible asymmetry in the material strength.
4. It provides no information about the strength of the material in different environments.
5. I provides no information about changes in the material strength due to the process of forming the material. A casting will have different properties than a forging or a sintered metal part.
Because of these disadvantages, the use of tensile strength in design needs to applied with a great deal of common sense.
Main Function and Usage
It is suitable for tensile,compression, bending , cutting , stripping, splitting and other testings for metal materials or non-metal materials.
Main Performance Characters
Door type frame structure, with double space.
It adopts circular tooth profile synchronous belts in the transmission part, ball screw as assistant transmission, conducting a stable transmission.
Driven by TECO servo motor, putting the movement of the cross beam from top to bottom, the testing takes it s own process step by step.
Adaptable Standard: GB,ISO,ASTM,DIN
