Tensile testing can be performed on most types of materials and gives information about yield strength, ultimate tensile strength, modulus of elasticity (stiffness), elongation, and other important properties.Ī tensile test is a reliable way to get data about how different processes may affect the performance of your final product – processes such as sterilization, extended aging periods, and exposure to various temperature and humidity conditions. It involves the linear stretching of a material until failure or some critical value is achieved. The shoulders allow the specimen to be gripped while the gauge length shows the deformation and failure in the elastic region as it is stretched under load. The reduced cross section gauge length of specific dimensions assists with accurate calculation of engineering stress via load over area calculation.Tensile testing is one of the most common ways of measuring material strength. Most specimens use either a round or square standard cross section with two shoulders and a reduced section gauge length in between.

The most commonly used specifications are BS EN ISO 6892-1 and ASTM E8M. Tensile test specimens are prepared in a variety of ways depending on the test specifications. This is known as the elastic or proportonal limit (also the yield strength). Once the material has been stretched to the point where it no longer returns to its original length and permanent deformation is shown, Hooke's Law no longer applies. The modulus of elasticity also known as Young's modulus measures the stiffness of a specimen whereby the material will return to its original condition once the load has been removed. How much it harderns with plastic defremation. It is commonly described Strain Hardening The percentage of elongation is calculated by the maximum gage length divided by the original gage length. Ductilityĭuctility relates to the elongation of a tensile test. These material properties can change depending on environment, for example in extreme hot or cold conditions. This may differ from the specimen's strength when breaking depending on if it is brittle, ductile or has properties of both.
The UTS is the maximum stress that a specimen is exposed to during testing. This is determined during testing over a measured gauge length via the use of devices known as extensometers. The devices may be either be mechanical clip on or video where non-contact is a limitation, e.g. The yield strength is the point at which plastic deformation occurs under stress.

This test method is used to determine yield strength, ultimate tensile strength, ductility, strain hardening characteristics, Young's modulus and Poisson's ratio. It is used to find out how strong a material is and also how much it can be stretched before it breaks. This is one of the most common mechanical testing techniques. Tensile Testing is a form of tension testing and is a destructive engineering and materials science test whereby controlled tension is applied to a sample until it fully fails.
