(II) Special Test Items:

1. Elastic coefficient is elastic Young's modulus

Definition: Ratio of normal stress component to normal strain in phase.

Is the coefficient of determination of material rigidity, the higher the value, the stronger the material.

2. Example limit: the load can be maintained in direct proportion to the elongation within a certain range, and the maximum stress is the specific limit.

3. Elastic limit: the maximum stress that the material can bear without permanent deformation.

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

5. Permanent deformation: After removing the load, the material is still residual deformation.

6. Yield point: when the material is stretched, the deformation increases and the stress remains unchanged. This point is the yield point.

Yield points are divided into upper and lower yield points, which are generally taken as yield points.

yield: If the load exceeds the scale limit, the load will no longer be proportional to the elongation. The load will drop abruptly and then, for a period of time, rise and fall and the elongation will change greatly. This phenomenon is called yield.

7. Yield strength: when tensile, the weight of permanent elongation reaching a specified value, divided by the original fault area of the parallel part, obtained by the quotient.

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

9. Effective elasticity and hysteresis loss:

In the tensile machine, at a certain speed will be the sample stretched to a certain elongation or stretched to the specified load, the test sample shrinkage recovery of work and work consumption ratio of the percentage, that is, effective elasticity;

The percentage of the energy lost during the test specimen's elongation and contraction and the work consumed during the elongation is the hysteresis loss.
