Universal material testing machine

The universal tensile testing machine is a new type of material testing machine that combines electronic technology with mechanical transmission. It has a wide and accurate loading speed and testing range, and has high accuracy and sensitivity in measuring load, deformation, and displacement. It can also perform automatic control tests for constant velocity loading, constant velocity deformation, and constant velocity displacement, and has the function of low cycle load cycling, deformation cycling, and displacement cycling.

Universal material testing machineMain function introduction:

Common testing items: (common display values and calculated values)

Tensile stress, tensile strength, tensile strength, elongation at break, tensile stress, elongation at constant stress, tensile stress value, tear strength, arbitrary point force value, arbitrary point elongation, pull-out force, adhesive force and peak calculation value, pressure test, shear peel force test, bending test, pull-out force and puncture force test.

Special testing items:

1. Coefficient of elasticity, also known as Young's modulus of elasticity, is defined as the ratio of the normal stress component to the normal strain in the same phase. To determine the coefficient of material rigidity, the higher the value, the stronger the material.

2. Proportional limit: Within a certain range, the load can maintain a proportional relationship with elongation, and the maximum stress is the specific limit.

3. Elastic limit: The maximum stress that a material can withstand without undergoing deformation.

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

5. Deformation: After removing the load, the material still retains deformation.

6. Yield point: When a material is stretched, the deformation increases while the stress remains constant, and this point is called the yield point. The yield point is divided into upper and lower yield points, and generally the upper yield point is taken as the yield point. Yield: When the load exceeds the proportional limit and elongation is no longer proportional, the load will suddenly drop, and then fluctuate up and down over a period of time, causing significant changes in elongation. This phenomenon is called yield.

7. Yield strength: The quotient obtained by dividing the load at which the elongation reaches a certain specified value by the original cross-sectional area of the parallel part during stretching.

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