The relationship between true strain $$\left( {{\varepsilon _T}} \right)$$ and engineering strain $$\left( {{\varepsilon _E}} \right)$$ in a uniaxial tension test is given as

$${\varepsilon _E} = \ln \left( {1 + {\varepsilon _T}} \right)$$

$${\varepsilon _E} = \ln \left( {1 - {\varepsilon _T}} \right)$$

$${\varepsilon _T} = \ln \left( {1 + {\varepsilon _E}} \right)$$

$${\varepsilon _T} = \ln \left( {1 - {\varepsilon _E}} \right)$$
