Resource type: Equation
Description: Engineering strain is the form commonly used in quantising, testing and stress-strain curves but does not take into account the reduction is cross-sectional area as a specimen plastically deforms. This is the true strain.

TeX format: \varepsilon_{t} = ln{(1 + \varepsilon)}

εt {\varepsilon_t} = True strain
ε {\varepsilon} = Engineering strain

Keywords: stress • strain • deformation • elastic • stiffness • Poisson's • true
