The performance and strength data measured by tensile testers are important in the selection of design and materials, purchase and sale of products, development of new products, quality control, and safety of equipment. During the research stage of product development, tensile testing is crucial in choosing the most appropriate materials. A tensile test machine can verify whether candidate materials pass the required strength and elongation requirements for a certain product.
In the metals industry, tensile testing provides an opportunity to discover new alloys, their qualities, and the possible uses they might have. This can lead to improved materials, which are beneficial to both manufacturers and end users. The use of a tensile strength tester in the quality control of products is also crucial.
It provides manufacturers a way to identify whether there are problems in their manufacturing line. It also ensures that what they deliver to customers is safe, of high quality, and adheres with industry and international standards. The cost of not complying with industry standards may not only be monetary. At worst, it could involve human cost. Performing regular tensile testing usually costs far less than the consequences brought about by using inappropriate materials or sale of substandard products.
Therefore, carrying out reliable and accurate tensile tests should be a priority.

The point of rupture 3 is when the material breaks and the stress-strain curve drops immediately back to zero.
For ductile materials, the tensile strength is the same as the ultimate strength point. Less ductile materials will break, or fracture, before they exhibit a neck, so the point of rupture is taken to be the tensile strength. Even the same material will show a different stress-strain curve across several tests, especially if there are varying factors such as temperature and speed of force loading.
The difference in stress-strain curves between ductile and brittle materials is greater. The MaterialsSceince video series by the Karlsruhe University of Applied Sciences in Karlsruhe, Germany gives a great demonstration of this difference here.

Imprint Data Protection Declaration. The percentage of elongation is calculated by the maximum gage length divided by the original gage length. It is commonly described. 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.
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. This is known as the elastic or proportonal limit also the yield strength. Tensile test specimens are prepared in a variety of ways depending on the test specifications. Most specimens use either a round or square standard cross section with two shoulders and a reduced section gauge length in between.
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 provides details of the tensile mechanical properties of a material.

Tensile testing can greatly reduce this danger by determining the engineering stress and other properties of a material or part. Tensile testing also gives designers and manufacturers data on new materials and their properties so they can determine qualities for future use.
