Resilience Modulus

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Resilience modulus, abbreviated as \( \mu \) (Greek symbol mu), also called modulus of resilience, is the amount of energy a material can absorb and still return to its origional shape.


Resilience Modulus Formula

\(\large{ \mu = \frac{ \sigma^2 }{ 2 \; E }  }\) 
Symbol English Metric
\(\large{ \mu }\)  (Greek symbol mu) = resilience modulus \(\large{\frac{lbf}{in^2}}\)  \(\large{N}\) 
\(\large{ \sigma }\)  (Greek symbol sigma) = yield strength \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ E }\) = Young's modulus \(\large{\frac{lbf}{in^2}}\) \(\large{N}\)
