Bulk modulus (K) measures resistance to uniform compression: K = -V(dP/dV), inverse of compressibility.

Trinn-for-trinn guide

  1. 1Input initial volume, pressure change, volume change
  2. 2Calculate bulk modulus
  3. 3Results show material stiffness under hydrostatic pressure

Inndata
Water: K ≈ 2.2 GPa (compressible)
Resultat
Steel: K ≈ 160 GPa (incompressible)
Water ~70× more compressible

Vanlige feil å unngå

  • Confusing with Young's modulus (uniaxial)
  • Not accounting for pressure effects on K

Ofte stilte spørsmål

How does bulk modulus relate to speed of sound?

Sound speed = √(K/ρ); higher K means faster sound.
