The tensile test is carried on _______ materials.

Explanation:

UTM:

A Universal Testing Machine is a machine that is used to perform standard tensile and compressive tests on materials, components, and structures.

It can be used to perform the following tests:

• Tensile Test
• Compressive Test
• Shear Test

Tensile Test: 

• Tensile Test are performed for several reasons. The results of tensile tests are used in selecting materials for engineering applications. Tensile properties frequently are included in material specifications to ensure quality. properties often are measured during development of new materials and processes, so that different materials and processes can be compared. Finally, tensile properties often are used to predict the behavior of a material under forms of loading other than uniaxial tension.
• The Strength of a material often is the primary concern. The strength of interest may be measured in terms of either the stress necessary to cause appreciable plastic deformation or the maximum stress that the material can withstand. These measures of strength are used, with appropriate caution (in the form of safety factors).
• in engineering design. Also of interest is the material's ductility, which is a measure of how much it can be deformed before it fractures. Rarely is ductility incorporated directly in de-sign rather, it is included in material specifica-tions to ensure quality and toughness. Low ductility in a tensile test often is accompanied by low resistance to fracture under other forms of loading.

Working Principle:

It is a load controlled machine and works on the principle of elongation/deformation of material on the application of load.
