Strain. It is defined as the change in length divided by the original length:
ε = ΔL / L
(For axial deformation ε is dimensionless; positive for extension, negative for compression. Shear strain is the angular distortion in radians. Engineering (nominal) strain uses ΔL/L; true strain uses the integral form ln(L/L0).)
