Tensile strength
Tensile Strength
Tensile strength (pronunciation: /ˈtɛnsaɪl ˈstrɛŋkθ/), also known as ultimate strength, is a measure of the maximum stress that a material can withstand while being stretched or pulled before breaking. The term is derived from the Latin word "tensio" meaning "to stretch" and the Old English word "strengþu" meaning "power, force, vigor".
Description
Tensile strength is a key factor in determining a material's durability and structural integrity. It is typically measured in units of force per unit area, such as Pascals (Pa), Newtons per square meter (N/m²), or pounds per square inch (psi).
Testing
Testing for tensile strength, often referred to as a tensile test, involves applying a controlled tension load to a sample of the material until it fractures or breaks. The maximum load applied during the test is recorded as the tensile strength of the material.
Factors Influencing Tensile Strength
Several factors can influence the tensile strength of a material, including its composition, temperature, rate of loading, and the presence of any defects or impurities.
