Elastic Modulus

Elastic Modulus

Elastic modulus (also known as 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

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

Where:

\(\large{ \lambda }\)  (Greek symbol lambda) = elastic modulus

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

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

Solve for:

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

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