Youngs modulus 3Youngs modulus 2Elastic modulus (Young's modulus), abbreviated as \(\lambda\) (Greek symbol lambda), also called modulus of elasticity, is the ratio of the stress applied to a body or substance to the resulting strain within the elastic limits.


Elastic Modulus formula

\(\large{ \lambda = \frac { \sigma } { \epsilon } }\) 


 Units English Metric
\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus \(\large{\frac{lbf}{in^2}}\) \(\large{MPa}\)
\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain \(\large{\frac{in}{in}}\) \(\large{\frac{mm}{mm}}\)
\(\large{ \sigma }\)  (Greek symbol sigma) = stress \(\large{\frac{lbf}{in^2}}\) \(\large{MPa}\)
