Calculate Percent Elongation (PE)



Formula

The formula to calculate the Percent Elongation is:

\[ \text{PE} = \frac{\text{FL} - \text{IL}}{\text{IL}} \times 100 \]

What is Percent Elongation?

Percent Elongation (PE) is a measure of how much a material can stretch before breaking. It is calculated by dividing the difference between the final length and the initial length by the initial length, then multiplying by 100. This value is expressed as a percentage and indicates the ductility of the material.

Example Calculation

Let's consider an example:

Using the formula to calculate the Percent Elongation:

\[ \text{PE} = \frac{12 - 10}{10} \times 100 = 20\% \]

This means that the Percent Elongation (PE) is 20%.
