The formula to calculate True Strain (\(\epsilon_T\)) is:
\[ \epsilon_T = \ln(1 + \epsilon) \]
Where:
True strain is the instantaneous elongation per unit length.
Engineering strain is the ratio of change in length to its original length.
Let's assume the following value:
Using the formula:
\[ \epsilon_T = \ln(1 + \epsilon) \]
Evaluating:
\[ \epsilon_T = \ln(1 + 0.01) \]
The True Strain is 0.0099503309.
