Youngs modulusYoungs modulus 1AYoung's modulus, abbreviated as Yo or E, also called elastic modulus, modulus of elasticity, and tension modulus, Young's modulus of elasticity, measures the stiffness of an elastic material.  The ratio of the longitudinal stress applied to a body or substance to the resulting longitudinal strain within the elastic limits.

 

Young's Modulus formulas

\(\large{ E = \frac { \sigma } { \epsilon } }\)   
\(\large{ E = \frac { S }   { \alpha \; \Delta T }   }\)  (restrained anchored pipe stress

Where:

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

\(\large{ S }\) = restrained anchored pipe stress

\(\large{ \epsilon }\)  (Greek symbol epsilon) = strain

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

\(\large{ \Delta T }\) = temperature differential

\(\large{ \alpha }\) = thermal expansion coefficient
