To calculate bulk modulus elasticity (stress), two essential parameters are needed and these parameters are Average Horizontal Stress (hav) and Vertical Stress (σv).
The formula for calculating the bulk modulus elasticity (stress):
k = hav / σv
Where;
k = Bulk Modulus of Elasticity (Stress)
hav = Average Horizontal Stress
σv = Vertical Stress
Let’s solve an example;
Given that the average horizontal stress is 15 and the vertical stress is 34. Find the bulk modulus of elasticity (stress)?
This implies that;
hav = Average Horizontal Stress = 15
σv = Vertical Stress = 34
So, k = hav / σv
k =Â 15Â /Â 34
k = 0.44
Therefore, the bulk modulus of elasticity (stress) is 0.44.
Calculating the Average Horizontal Stress when the Bulk Modulus Elasticity (stress) and the Vertical Stress are Given
hav = k x σv
Where;
hav = Average Horizontal Stress
k = Bulk Modulus of Elasticity (Stress)
σv = Vertical Stress
So, let’s solve an example;
Given that the bulk modulus of elasticity (stress) is 25 and the vertical stress is 8, find the average horizontal stress.
This implies that;

k = Bulk Modulus of Elasticity (Stress) = 25
σv = Vertical Stress = 8
Then, hav = k x σv
hav = 25 x 8
hav = 200
Therefore, the average horizontal stress is 200.

Calculating the Vertical Stress when the Bulk Modulus Elasticity (stress) and the Average Horizontal Stress are Given
σv = hav / k
Where;
σv = Vertical Stress
k = Bulk Modulus of Elasticity (Stress)
hav = Average Horizontal Stress
Let’s solve an example;
Given that the bulk modulus of elasticity (stress) is 18 and the average horizontal stress is 32. Find the vertical stress?
This implies that;
k = Bulk Modulus of Elasticity (Stress) = 18
hav = Average Horizontal Stress = 32
So, σv = hav / k
σv = 32 / 18
σv = 1.77
Therefore, the vertical stress is 1.77.
