Accordingly, how do you calculate percent elongation?

Percent Elongation - The strain at fracture in tension, expressed as a percentage = ((final gage length – initial gage length)/ initial gage length) x 100. Percent elongation is a measure of ductility.

Subsequently, question is, what is elongation in material? Elongation is a measure of deformation that occurs before a material eventually breaks when subjected to a tensile load. Elongation due to expansion can also occur when a material undergoes an increase in temperature, or if both an axial force and a high temperature act simultaneously upon a material.

Simply so, why Is percent elongation important?

The percent elongation is a property of the material, which provides a value of its ductility, i.e. of its capability of undergoing plastic deformation when kept under load before breaking. If the material is ductile, therefore with a high A% (or El%), during a crash it will deform plastically.

What does elongation mean in steel?

Elongation stands for a mechanical property of metal i.e. the degree to which a material is supposed to be delivered, stretched, or compressed prior to rupture. It is a point among tensile strength and yield strength and is presented as a percentage of the original length.
