G is shear modulus.
E is elasticity modulus.
E=2G(1+Poisson's ratio)
Then G=E/2*(1+Poisson's ratio).
Substitution the value in the above equation and result will be less than half.

We know,
E = 2N(1+u).
>N = (E/2)*(1/(1+u)).
Where, (1+u)~1.
Hence, N = E/2.
E = 2N(1+u).
>N = (E/2)*(1/(1+u)).
Where, (1+u)~1.
Hence, N = E/2.

E=2G(1+ posion ratio).
Example, for steel E =210Gpa,
And poison ratio up to . 33.
210= 2G (1+.33)= G= 78.94 so G is less than 1/2 of E (210GPa).
