Elasticity

Elasticity ( \(E\) ) or ( \(ELAS\) ) measures the stiffness of an elastic material.  Elasticity can deformed body and return to its original shape when the forces exerted are removed.

Elasticity Formula

\(\large{ E = \frac {  {v_l}^2   \rho \; \left( 1 \;+\; Po  \right) \; \left( 1 \;-\; 2Po  \right) }  { 1 \;-\; Po }  }\)         

 

Where:

\(\large{ E }\) = elasticity

\(\large{ v_l }\) = longitudinal velocity

\(\large{ \rho }\)  (Greek symbol rho) = density

\(\large{ Po }\) = Polsson's ratio
