Explanation of 9 test items of wire tension testing machine

টেনশন পরীক্ষকYou can test a variety of materials such as plastic, stone, and steel. The following is an understanding of the test of the wire tension testing machine.

1. Elasticity limit: The stress that the material can withstand without deformation.

2. The elastic coefficient is the elastic Young's modulus

3. Deformation: After removing the load, the material remains deformed.

4. Proportional limit: The load can be maintained in a proportional relationship with elongation within a certain range, and its stress is the proportional limit.

5. Steel Wireটেনশন পরীক্ষকelastic deformation: After removing the load, the deformation of the material completely disappears.

6. Effective elasticity and hysteresis loss of wire tensioning machine: When the sample is stretched to a certain elongation or stretched to a specified load at a certain speed, the percentage of the ratio of the work recovered when the sample is contracted and the work consumed when the extension is measured is effective elasticity; the percentage of the ratio of the energy lost during the elongation and contraction of the sample is measured to the work consumed when the sample is stretched, which is hysteresis loss.

7. Yield point of wire tensioner: When the material is stretched, the deformation increases rapidly and the stress remains unchanged. This point is the yield point. The yield point is divided into upper and lower yield points, and generally the above yield point is used as the yield point.

Yield: The load exceeds the proportion limit and is no longer proportional to the elongation. The load will suddenly drop, and then rise and fall over a period of time, and the elongation will change significantly. This phenomenon is called yield.

8. Yield strength: When stretching, the load weight at which the elongation reaches a certain specified value is divided by the original cross-sectional area of ​​the parallel part, and the quotient obtained.

9. Steel Wireটেনশন পরীক্ষকThe value of spring K: the ratio of the force component in phase with the deformation and the deformation.
