Cum se calculează Bulk Modulus

Ce este Bulk Modulus?

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

Ghid pas cu pas

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

Exemple rezolvate

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

Greșeli frecvente de evitat

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

Întrebări frecvente

How does bulk modulus relate to speed of sound?

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