Ultimate tensile strength (or just tensile strength for short) is an important property of materials<\/a> to determine their mechanical performance. It is the ability of a material to resist tearing due to tension<\/strong>. This parameter applies to all types of materials such as wires, ropes, metal beams, etc.<\/p>\n

What Is Tensile Strength?<\/h2>\n

Imagine a strip of paper being pulled at its two ends with your fingers. You are applying a tensile force on the strip. When this tensile force crosses a certain threshold, the paper tears. The tensile stress at which this takes place is the tensile strength of that material, in this case paper.<\/p>\n

When excessive tension is applied, both ductile, as well as brittle materials will approach a point of failure. Initially there will be a uniform deformation observed. All throughout the body of the material, its length will increase while its width reduces at the same rate.<\/p>\n

Ultimate tensile strength is the amount of stress that pushes materials from the state of uniform plastic deformation to local concentrated deformation. The necking phenomenon begins at this point.<\/p>\n

Ultimate tensile strength is an intensive property. In other words, it does not depend on the size of the sample. The same material with varying cross-sectional area will have the same value of tensile strength.<\/p>\n

As this type of fracture in a system can cause failure and possibly endanger life, it is imperative that this parameter is considered while selecting appropriate materials for an application.<\/p>\n
