How to Calculate and Solve for Young’s Modulus | Rock Mechanics

The image above represents young’s modulus. To calculate young’s modulus, two essential parameters are needed and these parameters are axial stress (σa) and axial strain (εa).

The formula for calculating the young’s modulus:

E = σa / εa

Where:

E = Young’s Modulus
σa = Axial Stress
εa = Axial Strain

Let’s solve an example;
Given that the axial stress is 65 and the axial strain is 45, calculate for the young’s modulus.

This implies that;

σa = Axial Stress = 65
εa = Axial Strain = 45

Then, E = σa / εa
E = 65 / 45
E = 1.44

Therefore, the young’s modulus is 1.44.

Calculating the Axial Stress when the Young’s Modulus and the Axial Strain are Given

σa = E x εa

Where;

σa = Axial Stress
E = Young’s Modulus
εa = Axial Strain

Let’s solve an example;
Given that the young’s modulus is 25 and the axial strain is 10, calculate the axial stress.

This implies that;

E = Young’s Modulus = 25
εa = Axial Strain = 10

So, σa = E x εa
σa = 25 x 10
σa = 250

Therefore, the axial stress is 250.

Calculating the Axial Strain when the Young’s Modulus and the Axial Stress are Given

εa = σa / E

Where;

εa = Axial Strain
E = Young’s Modulus
σa = Axial Stress

Let’s solve an example;
Given that the young’s modulus is 7 and the axial stress is 35, calculate the axial strain.

This implies that;

E = Young’s Modulus = 7
σa = Axial Stress = 35

Then, εa = σa / E
εa = 35 / 7
εa = 5

Therefore, the axial strain is 5.
