While papers are tested for different properties, such as absorption, softness, puncture resistance, tear strength, and more, the tensile strength test is given the highest priority.
The tensile test refers to measuring the tensile strength, stretch or elongation, yield, and breaking strength of the paper. It determines if the paper is strong and how much it can be stretched without breaking, or before it finally breaks. In the following article, we will throw light on the common tensile testing results and measurements that are achieved on the tensile strength testing machine.
Crucial Tensile Testing Measurements & Results
Tensile Strength
Tensile strength refers to the stress that’s determined during the tensile test. This stress is calculated as the amount of force divided by the cross-sectional area of the specimen.
Elasticity Or Stretch
Stretch or elasticity refers to the ability of the paper to be pulled to stress. Plus, when the stress is removed, it returns to its original length without getting deformed.
Elasticity Percentage
The elasticity percentage refers to the maximum degree of stress the paper can resist before changing its shape or undergoing any deformity.
Yield Strength
Yield strength measures the stress that can cause the permanent deformation of the paper. In other words, it refers to that stage where the stress has gone beyond the elastic stress limit.
Stiffness
The stiffness property of the paper refers to its ability to withstand deformation when excessive pressure is applied to it. It is also referred to as the bending resistance of the paper.
Modulus of Elasticity
The modulus of elasticity refers to the determination of the paper’s stiffness. After the test is performed, if the stiffness is more, there will be less deformation and vice versa.
Conclusion
When it comes to understanding the tensile strength of the paper, manufacturers also consider another crucial aspect called the tearing strength. This property is measured using a tearing strength tester. Visit UEC to know more about this tester and other paper property testing machines.
