Bulk Modulus Calculator












How This Is Calculated



K=pΔV/V0
where:

K   =   Bulk Modulus   (Pa or N/m²)

p   =   Applied Pressure   (Pa or N/m²)

ΔV/V0   =   Fractional Change in Volume   (dimensionless)


Assumptions



  • 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.
