Calcolatrice Deformazione — Formula
## Engineering Strain
Strain measures the deformation of a body relative to its original size.
### Formula
**epsilon = delta_L / L_0**
where delta_L is the change in length and L_0 is the original gauge length. Strain is dimensionless but is often expressed in microstrain (x 10^6) or as a percentage. Tensile strain is positive; compressive strain is negative.

Esempio Risolto
A 500 mm gauge length bar elongates by 0.5 mm under load.
- epsilon = 0.5 / 500 = 0.001 mm/mm
- As percentage: 0.001 x 100 = 0.1%
- In microstrain: 0.001 x 10^6 = 1000 microstrain
