Ductility Measurement - Percent Elongation

Introduction to Ductility Measurement - Percent Elongation Calculator

Ductility is a measure of a material's ability to undergo significant plastic deformation before rupture. One of the measures of ductility is percent elongation, which gauges how much a material can stretch beyond its original length before it breaks. The percent elongation is calculated as the increase in the length of a sample during a tensile test, expressed as a percentage of the initial length. This calculation is important in materials science and engineering, especially when assessing the performance of metals and polymers under stress.

Parameter usage:

• initialLength = original length of the sample before testing
• finalLength = the length of the sample after fracture

Output:

• percentElongation = percent increase in length of the material (ductility metric)

Data validation

Both initialLength and finalLength should be positive numbers with finalLength being greater than initialLength.

Summary

The calculator takes the original and final lengths of a material sample after a tensile test and provides a percentage increase, indicating the material's ductility.
