How to Calculate and Solve for Young’s Modulus | Rock Mechanics The image above represents young’s modulus.

To compute for 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

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 is 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 for the axial stress?

This implies that;

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

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 is 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 for the axial strain?

This implies that;

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

εa = σa / E
εa = 35 / 7
εa = 5

Therefore, the axial strain is 5.
