engineering recuitment NMDC Junior Officer (Trainee) Mock Test 2024 Strength of Materials Elastic Limit and Constants
For isotropic materials, the modulus of Elasticity in tension and shear (E and G) are related to the Poisson's ratio (v) as follows
1
E = \(\rm\frac{G}{2(1+\nu)}\)
2
G = \(\rm\frac{E}{2(1+\nu)}\)
3
G = \(\rm\frac{E}{2(1-\nu)}\)
4
E = \(\rm\frac{G}{2(1-\nu)}\)
