What tests can the stripper tester do? Dongguan Haida Instrument 400-071-1808/0769-89280808 Peel tester can do what tests, today we talk about this issue: 1. Proportional limit: The load can maintain a proportional relationship with the elongation within a certain range. The maximum stress is the limit ratio. 2. Elasticity modulus is the definition of elastic Young's modulus: 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. 3. Elastic deformation: After the load is removed, the deformation of the material disappears completely. 4. Elastic limit: The maximum stress that a material can withstand without permanent deformation. 5. Permanent deformation: After the load is removed, the material remains deformed. 6, Yield strength: When stretching, the permanent elongation reaches a specified load, divided by the original cross-sectional area, the quotient. 7. 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, and generally the yield point above the yield point. Yield: When the load exceeds the proportional limit and the elongation is no longer proportional, the load will suddenly drop, and then over time, ups and downs, and the elongation will change greatly. This phenomenon is called yielding. 8, spring K value: the ratio of the force component and deformation of the same phase and deformation. 9.Effective elasticity and hysteresis loss: When the specimen is stretched to a certain elongation or stretched to a specified load at a certain speed on a yield strength tester, the recovered work at the time of shrinkage of the specimen and the consumption at the time of elongation are measured. The percentage of the work ratio is the effective elasticity; the percentage of the ratio between the energy lost when the sample is stretched and contracted and the work consumed when it is stretched is the hysteresis loss.
