Tensile Strength Testing Equipment

Tensile Strength Testing Equipment adopts the mechanical and electrical integration design, mainly composed of the measuring force sensor, transmitter, microprocessor, load driving mechanism, computer and color inkjet printer.   The plastic tension tester applied force on the sample.Special tests for stretching, bending,compression or shear are classified according to the direction of the strain in the sample and the speed of the force.The basic test is performed by a standard plastic tensile testing machine.They are usually loaded at a speed range of 0.1mm/min to 500mm/min, and different materials require different test speeds.

(ii) special test items:

1. Elastic coefficient is young's modulus of elasticity

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

2. Proportion limit: the relationship between load and elongation can be maintained in a certain range, and the large stress is the ratio limit. 

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

4. Elastic deformation: the deformation of the material completely disappears after the load is removed. 

5. Permanent deformation: after the load is removed, the material still remains deformed. 

6. Yield point: when the material is stretched, the deformation increases rapidly but the stress remains unchanged. This point is the yield point.The yield point is divided into upper yield point and lower yield point. 

Yield: the load beyond the proportional limit is no longer proportional to the elongation, the load will drop suddenly, and then in a period of time, up and down, elongation greater change, this phenomenon is called yield. 

7. Yield strength: the load at which the permanent elongation reaches a specified value at stretching, divided by the original area of the parallel part, the quotient obtained. 

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

9. Effective elasticity and hysteresis loss:

When the specimen is stretched to a certain elongation rate or to a specified load at a certain speed on a tension machine, the percentage of the work recovered when the specimen contracts and the work consumed when the specimen is stretched is determined to be effective elasticity.The hysteresis loss is defined as the percentage of the energy lost during the elongation and contraction of the specimen to the work consumed during the elongation.
