5、 Testeable items:

（1） Common testing items: (common display values and calculated values)

● Tensile stress ● Tensile strength

● Tensile strength ● Tensile elongation

● Constant tensile stress ● Constant elongation at constant stress

● Fixed stress value ● Tear strength

● Force value at any point ● Elongation at any point

● Extraction force ● Adhesive force and peak calculation value

● Pressure Test ● Adhesive and Peel Force Test

● Bending test ● Pull out force puncture force test

（2） Special testing items:

1. Elastic coefficient, also known as Young's modulus of elasticity

Definition: The ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

2. Limitation: Within a certain range, the load can maintain a proportional relationship with elongation, and its stress is called the specific limit.

3. Elastic limit: The stress that a material can withstand without prolonged deformation.

4. Elastic deformation: After removing the load, the deformation * of the material disappears.

5. Long term deformation: After removing the load, the material still retains deformation.

6. Yield point: When a material is stretched, the deformation increases while the stress remains constant, and this point is called the yield point. The yield point is divided into upper and lower yield points, and generally the upper yield point is taken as the yield point.

Yield: When the load exceeds the proportional limit and elongation is no longer proportional, the load will suddenly drop, and then fluctuate up and down over a period of time, causing significant changes in elongation. This phenomenon is called yield.

7. Yield strength: The quotient obtained by dividing the load at which the elongation rate reaches a certain specified value during stretching by the original cross-sectional area of the parallel part.

8. Spring K value: the ratio of the force component in phase with the deformation to the deformation.

9. Effective elasticity and hysteresis loss.

On a tensile machine, when the sample is stretched at a certain speed to a certain elongation or to a specified load, the percentage of the recovered work during shrinkage and the consumed work during stretching is measured as the effective elasticity; The percentage of the energy lost during the elongation and contraction of a sample compared to the work consumed during elongation is called hysteresis loss.
