Strain Energy

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

strain energy 1Strain energy, abbreviated as U, is the energy stored in an elastic body of the material undergoing deformation. 


Strain Energy formula

\(\large{ U = \frac{ 1 }{ 2 } \; \left( \frac{V}{E}  \right)  \; \sigma^2 }\)   


\(\large{ U }\) = strain energy

\(\large{ \sigma }\)  (Greek symbol sigma) = stress

\(\large{ V }\) = volume

\(\large{ E }\) = Young's modulus
