Longitudinal strain is the fractional change in length of an object when a deforming force is applied along its length. It is a measure of how much an object stretches or compresses relative to its original length.
It is calculated as the ratio of the change in length ($\Delta L$) to the original length ($L_0$):
$$ \epsilon = \frac{\Delta L}{L_0} $$
Where:
$\epsilon$ (epsilon) represents the longitudinal strain.
$\Delta L$ is the change in length (final length - original length).
$L_0$ is the original length of the object.
Since it is a ratio of two lengths, longitudinal strain is a dimensionless quantity and therefore has no units.
