The advantage of using true strain is that the total true strain is equal to the sum of the incremental strains.

The advantage of using true strain is that the total true strain is equal to the sum of the incremental strains. Correct Answer True

The statement is true, Consider this with this example. A rod on 50 mm length with initial length is elongated in 3 steps as shown in the diagram: Step 1 = 5mm Step 2 = 5.5 mm Step 3 = 6.05 mm Calculate the engineering strain in each step: Step 1 = 5/50 = 0.1 step 2 = 5.5/55 = 0.1 Step 3 = 6.05/60.5 = 0.1 So total strain => 0.1+0.1+0.1=0.3 Now calculate the engineering strain in single step= 16.55/50=0.331. So, the strain value calculated in steps and all together for the same specimen is different. But in the case of true strain calculation, it will be the same in both cases.
