The image above represents true strain. To calculate true strain, two essential parameters are needed and these parameters are Final Length at Breakage (l1) and Initial Length before Breakage (l0).
The formula for calculating true strain:
εT = In(l1/l0)
Where:
εT = True Strain
l1Â = Final Length at Breakage
l0Â = Initial Length before Breakage
Given an example;
Find the true strain when the final length at breakage is 42 and the initial length before breakage is 8.
This implies that;
l1 = Final Length at Breakage = 42
l0 = Initial Length before Breakage = 8
εT = In(l1/l0)
So, εT = In(42/8)
εT = In(5.25)
εT = 1.658
Therefore, the true strain is 1.658.
