Tensile Testing
Tensile testing is a common denominator for a range of test processes that yield information about the tensile strength, yield strength, compression and ductility of the material under study. It also covers flexure tests, as well as shear and torsion tests.
A so-called Universal Testing Machine (UTM) allows for performing all tests mentioned above. This makes the UTM ideal for performing complex tasks in the field of material and component testing and the solution for demanding testing applications, whether in quality control or for research projects. In combination with climate chambers, the evolution of mechanical parameters during product lifetime can be investigated.
A UTM or tensile testing machine is also known as a tensiometer.
By means of a loadcell, the change in force is recorded that could indicate a failure or loss of strength of the specimen tested. In combination with the travelled distance of the grips, various mechanical parameters can be quantified.
A tensile testing machine is used to perform testing in accordance with several common ISO, ASTM and automotive standards, e.g. ISO 527, ASTM D412, ASTM F88, ASTM A370 and a diversity of other methods.
