What is Tension Test?
Tension Testing is another name known for the tensile testing. It is fundamental material science in which sample is subjected to controlled amount of tension in opposing direction until it fails. The result of the test is commonly used to select the appropriate material for the required application. The tensile test is performed to maintain the quality of the final product and to analyze that how the material will perform when they are subjected to tension forces.
Properties Measured by Tension Test
Properties that can be measured with the results of tension test are elongation strength, tensile strength, and stress in materials. Moreover, these properties are used to further calculate the young’s modulus, yield strength, strain hardening of the material and many other characteristics. The tension test is commonly used to obtain the mechanical characteristics of the materials such as composite materials, rigid plastics, metals, rubbers, fabrics, and many more. The tension test can be performed easily using high-quality of the tensile testing machine.
How to Prepare the Sample for Tension Test?
The test specimen to perform the tension test is a highly standardized cross section sample. The sample is prepared in the shape of dumbbell using Dumbbell cutting die with larger ends The larger ends of the sample are used to clamp both the ends of the sample between the provided jaws of the tensile machine firmly. Whereas the middle area of the sample has a smaller cross section from where the sample deforms or fails when tension is applied to it.
Tension Testing Machine by Presto
Presto’s Tension/Tensile testing machine is designed to evaluate the tensile strength of different products that are manufactured in different production verticals. The testing equipment works on the basis of Constant Rate of Traverse principle. The testing machine comprises of two jaws namely upper jaw and lower jaw. One of the jaw of the machine is kept stationary with a load cell, and the other end is movable. The movable jaw of the device moves with the fixed rate of speed (it can be move with variable speed if the device is provided with VFD drive) to measure the tension strength of the material.
