Elongation Percentage

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Elongation percentage, abbreviated as E_p, a dimensionless number, is the percentage of elongation at the fracture.

 

Elongation Percentage Formula

\(\large{ E_p = \frac{  \left( l_f \;-\; l_i \right) \; 100   }{ l_i }  }\) 
Symbol English Metric
\(\large{ E_p }\) = elongation percentage \(\large{ dimensionless }\)  
\(\large{ l_i }\) = initial length \(\large{ ft }\) \(\large{ m }\)
\(\large{ l_f }\) = length of fracture \(\large{ ft }\) \(\large{ m }\)
