What aspects of the film are tested by the traction machine

The traction machine as a test instrument has a very important application in testing the film, and the following aspects The film must be tested:
1 .Elastic deformation: under the action of external force, the shape and size of the material will change and become deformation. The complete recovery of the deformation after removing the external force is called elastic deformation. bpPTextile Testing Instruments, Testing Equipment Manufacturer
2. Static Tensile Plasticity Parameters: The ability of the material to deform irreversibly before breaking is called plasticity. The plastic index is the maximum relative plastic deformation when the metal breaks, and commonly the elongation δ in stretching is used. bpPTextile Testing Instruments, Testing Equipment Manufacturer

3. Tensile Strength: This is the maximum nominal tensile stress that the specimen will withstand before rupturing, also known as the yield strength, divided by the maximum load Fb,which is carried by the sample through the initial transverse area So the cross-sectional area So results. bpPTextile Testing Instruments, Testing Equipment Manufacturer
4. Modulus of Elasticity: This is an index characterizing the material's resistance to elastic deformation and its value is equal to the slope of the straight line segment on the stress-strain curve (unit is GPa). bpPTextile Testing Instruments, Testing Equipment Manufacturer
5. True ultimate strength: Divide the axial tensile stress F by the instantaneous actual cross-sectional area S of the specimen to get the true stress expressed by σt. bpPTextile Testing Instruments, Testing Equipment Manufacturer
6. Yield Strength: refers to the phenomenon that the material undergoes macroscopic plastic deformation, ie the stress does not increase or vary near a certain stress level and the specimen continues to generate strain. bpPTextile Testing Instruments, Testing Equipment Manufacturer
