engineering recuitment TSPSC AEE Civil Mock Test 2022 Strength of Materials Simple Stress and Strain Stress and Strain
The relationship between true shear stress, σ and engineering stress σ0 is given by (where, ϵ is the conventional strain)
1
\(\frac{\sigma }{{{\sigma _0}}} = 1 + \in \)
2
\(\frac{\sigma }{{{\sigma _0}}} = \frac{1}{{{{(1 + \in )}^2}}}\)
