Elastic Modulus

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Elastic modulus, abbreviated as $$\lambda$$, 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

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

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

Solve for:

$$\large{ \epsilon = \frac { \sigma } { \lambda } }$$

$$\large{ \sigma = \lambda \; \epsilon }$$
