The image above represents modulus of elasticity. To calculate modulus of elasticity, two essential parameters are needed and these parameters are Shear Modulus (G) and Poisson’s Ratio (V).
The formula for calculating modulus of elasticity:
E = 2G(1 + V)
Where:
E = Modulus of Elasticity
G = Shear Modulus
V = Poisson’s Ratio
Given an example;
Find the modulus of elasticity when the shear modulus is 28 and the poisson’s ratio is 4.
This implies that;
G = Shear Modulus = 28
V = Poisson’s Ratio = 4
E = 2G(1 + V)
E = 2(28)(1 + 4)
So, E = 2(28)(5)
E = (56)(5)
E = 280
Therefore, the modulus of elasticity is 280 Pa.
Calculating the Shear Modulus when the Modulus of Elasticity and the Poisson’s Ratio are Given
G = E / 2(1 + V)
Where:
G = Shear Modulus
E = Modulus of Elasticity
V = Poisson’s Ratio
Let’s solve an example;
Find the shear modulus when the modulus of elasticity is 40 and the poisson’s ratio is 3.
This implies that;

E = Modulus of Elasticity = 40
V = Poisson’s Ratio = 3
G = E / 2(1 + V)
G = 40 / 2(1 + 3)
That is, G = 40 / 2(4)
G = 40 / 8
G = 5
Therefore, the shear modulus is 5.
Calculating the Poisson’s Ratio when the Modulus of Elasticity and the Shear Modulus are Given
V = (E / 2G) – 1
Where:
V = Poisson’s Ratio
E = Modulus of Elasticity
G = Shear Modulus
Let’s solve an example;
Find the poisson’s ratio when the modulus of elasticity is 30 and the shear modulus is 3.
This implies that;
E = Modulus of Elasticity = 30
G = Shear Modulus = 3
V = (E / 2G) – 1
V = (30 / 2(3)) – 1
Then, V = (30 / 6) – 1
V = 5 – 1
V = 4
Therefore, the poisson’s ratio is 4.
