Special test items

1. Elastic coefficient is the elastic Young’s modulus Definition: The ratio of normal stress components to normal strain in the same phase. In order to determine the coefficient of stiffness of the material, the higher the value, the stronger the material.

2. Proportional Limit: The relationship between load and elongation can be maintained in a certain range, and the maximum stress is the specific limit.

3. Elasticity Limit: Maximum stress for material to withstand pull-out force puncture test without permanent deformation.

4. Elastic Deformation: When the load is removed, the deformation of the material disappears completely.

5. Permanent Deformation: After removing the load, the material remains deformed.

6. Yield point: When a material is stretched, the deformation increases, and the stress remains unchanged. This point is the yield point. The yield point is divided into upper and lower yield points, and the above yield points are generally regarded as yield points. Yield: When the load exceeds the proportional limit, it is no longer proportional to the elongation. The load will drop suddenly. Then, over a period, it will fluctuate up and down, and the elongation will change greatly. This phenomenon is called yield.

7. Yield Strength: The quotient obtained by dividing the permanent elongation to a specified load by the original cross-section area of the parallel part in tension.

8. Spring K Value: Ratio of Force Component in Phase with Deformation to Deformation.

9. Effective Elasticity and Lag Loss: On a tension machine, when the specimen is stretched to a certain elongation or to a specified load at a certain speed, the percentage of the work recovered during shrinkage and the work consumed during stretching is determined as effective elasticity; and the percentage of the work lost during elongation and shrinkage to the work consumed during elongation is determined as hysteresis loss.
