(two)Tension testerExtraordinary Test Project:

1. The elastic coefficient is elastic Young's module

Definition: The ratio of normal stress weight to normal strain in the same phase. To determine the coefficient of rigidity of the data,

The higher the value, the stronger the data.

2. Proportional limit: The load can be maintained in a proportional relationship with elongation within the inevitable limitation, and its stress is the proportional limit.

3. Elasticity limit: The stress that is acceptable to the data without eternal deformation.

4. Elastic deformation: After removing the load, the deformation of the data completely disappears.

5. Eternal deformation: After removing the load, the data remains deformation.

6. Compliance point: When the data is stretched, the deformation increases rapidly and the stress remains unchanged. This point is the compliance point. The surrender point is divided into the surrender point.

The above submission point is used as the submission point.

yield: The load exceeds the proportion limit and is no longer proportional to the elongation, the load will suddenly drop, and then within a period of time,

The upper and lower parts are rugged, and the elongation and hair changes significantly. This scene is called surrender.

7. Flexibility: When stretching, the load weight of the elongation reaches a certain regular value, divided by the original cross-sectional area of ​​the parallel part,

The business of what you get.

8. Spring K value: The ratio of the effect force weight and deformation in the same phase as the deformation.
