Step 1: Calculate the bulk modulus.
Bulk modulus expresses the strength of the material when external force is applied in the axial direction, producing stress.
The external pressure p (force times area over which the force is applied, expressed in MPa) applied to the material equals the dilation (a unitless number) times the bulk modulus K (expressed in MPa).
As p = K times dSs, the bulk modulus K is determined as p divided by dSs. , Shear modulus expresses the strength of the material when external force is applied in the perpendicular direction, producing strain.
The external pressure p (force times area over which the force is applied, expressed in MPa) applied to the material equals the dilation (a unitless number) times the shear modulus G (expressed in MPa).
As p = G times dSn, the bulk modulus G is determined as p divided by dSn. , Stressing a material will cause a proportional strain and vice versa.
Young's modulus describes the relationship between stress and strain in the material.
It is a linear relationship up to the yield point of the material.
Young's modulus E equals stress divided by strain. -
Step 2: Figure out the shear modulus.

Step 3: Determine the Young's Modulus.
