Material tensile testing using the DIC, can measure the displacement and strain in the necking region of a dog bone tensile test specimen. By doing this, the test determines how much it can elongate. DIC offers significant advantages (non-contact and full field) over conventional techniques such as extensometer/strain gauge for determining the true mechanical properties of the material and for a better understanding of component behavior.
With the DIC system, displacement and strain of standard dog bone tensile test specimens can be easily tested under non-contact, full field and real time conditions, even with the Poisson ratio of the material.
Why Perform a Material tensile test?
Relevant and crucial data can be discovered and obtained about a specimen from material tensile testing. By measuring the displacement and strain of the specimen its properties can be captured. After the stress/strain curve data is plotted on a graph, the curve data depicts how the specimen reacts to the applied forces. To discover the breaking point or failure of the test sample, it helps to determine the ultimate tensile strength (UTS) which is the maximum stress that a specimen sustains during the test. Other factors to take in consideration while measuring are the yield strength and modulus of elasticity.
