Dongguan Haida Instrument 400-071-1808/0769-89280808
In addition to the above tests, you can do the following special test items:
1.
Elasticity coefficient is elastic Young's modulus
Definition: The ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material stiffness, the higher the value, the stronger and tougher the material.
2.
Proportional limit: The load can maintain a proportional relationship with the elongation within a certain range. The maximum stress is the limit ratio.
3.
Elasticity limit: The maximum stress that a material can withstand without permanent deformation.
4.
Elastic deformation: After 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 the material is stretched, the deformation increases and the stress does not change. This point is the yield point. The yield point is divided into the upper and lower yield points.
The above yield point is generally used as the yield point.
Yield (yield): load ratio exceeds the threshold is no longer proportional to the elongation, would dump the load, and then a period of time,
Ups and downs, great changes in elongation, this phenomenon is called yield.
7.
Yield strength: The quotient obtained when the permanent elongation reaches a certain specified value when stretched, divided by the original cross-sectional area of ​​the parallel section.
8.
Spring K value: The ratio of the force component and deformation in the same phase as the deformation.
9.
Effective elasticity and hysteresis loss: on the yield strength tester, the specimen is stretched to a certain extent at a certain speed
When measuring the rate or stretching to the specified load, measure the percentage of work recovered when the sample shrinks and the work consumed when stretched.
Effective elasticity; the percentage of the ratio of the energy lost during elongation and contraction of the sample to the work consumed during elongation, ie,
Lag loss.
