where:
K = Bulk Modulus (Pa or N/m²)
p = Applied Pressure (Pa or N/m²)
ΔV/V0 = Fractional Change in Volume (dimensionless)
- The material behaves linearly and elastically.
- Deformations are small (for large strains the linear relationship between shear stress and strain may not hold).
- Material is homogeneous.
- The material is isotropic.
