company news about The function and effect of tensile testing machine

The function and effect of tensile testing machine：

Testing machine is a relatively broad term. According to different classification methods, testing machine is differentiated into tensile testing machine, universal testing machine, electronic universal testing machine, hydraulic universal testing machine, horizontal tensile testing machine, tensile testing machine, press and so on. It comes down to the fact that many models are the same, because a tensile testing machine can complete many kinds of experiments.

Ordinary LCD tensile testing machine can test the data as follows:

1. Tensile stress -- tensile strength

2. Strength at break -- elongation at break

3. Constant stress -- constant stress elongation

4. Constant stress force value -- tearing strength

5. Arbitrary point of force -- arbitrary point elongation

6. Extraction force -- adhesion force and the calculated value of peak value

7. Pressure experiment -- shear force stripping force experiment

8. Bending experiment -- drawing force puncture force experiment

9. Select additional force sensor to expand the measuring range;

10. The adjustment range of force control rate can also be selected according to the stress rate, stress rate = force control rate/original cross-sectional area of the sample;

11. The adjustment range of deformation rate can also be selected according to the strain rate, which is the deformation rate/the original standard distance of the sample;

12. The force control rate and deformation rate are related to the material of the sample, and the range can not exceed the adjustment range of displacement rate;

13. In order to avoid the force sensor to produce ** deformation, in the long time holding test, the test force ** do not exceed 50% of the full range of the sensor;

14. The effective drawing space is the test space after the standard Lashen fixture is installed. If the fixture is different, its value will be different
