5、 Testable items

(1) General test items: (general display value and calculated value)

Tensile stress ????? ● tensile strength

● breaking strength ????? Elongation at break

● constant extension stress ????? ● constant stress elongation

Constant stress value ??? ● tear strength

Force value at any point ??? ● elongation at any point

● extraction ???????? Adhesion force and peak value

Pressure test ?????? ● adhesion and stripping force test

● bending test ?????? Pull out force puncture force test

(2) Special test items:

one The elastic coefficient is young's modulus of elasticity

The ratio of normal stress to normal stress in the same direction. The higher the coefficient of rigidity, the stronger the material is.

two Proportional limit: load in a certain range and elongation can maintain a proportional relationship, its * stress is the ratio limit.

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

four Elastic deformation: after removing the load, the deformation of the material completely disappears.

five Permanent deformation: after removing the load, the material still has residual deformation.

six Yield point: when the material is stretched, the deformation increases and the stress remains unchanged, which is the yield point. The yield point is divided into upper and lower yield points, and the upper yield is generally used as the yield point.

Yield( yield ): when the load exceeds the proportion limit, it is no longer proportional to the elongation. The load will drop suddenly, and then fluctuate up and down in a period of time, and the elongation will change greatly. This phenomenon is called yield.

seven Yield strength: the quotient of the load when the permanent elongation reaches a specified value, divided by the original sectional area of the parallel part.

eight Spring K Value: the ratio of force component in phase with deformation to deformation.

nine Effective elasticity and hysteresis loss:

When the sample is stretched to a certain elongation or a specified load at a certain speed on the tensile machine, the percentage of the ratio of the work recovered during shrinkage to the work consumed during stretching is determined as the effective elasticity; the percentage of the ratio of the energy lost during the elongation and contraction to the work consumed during the elongation is the hysteresis loss.
