bulk modulus from pressure and volume change calculator online

Use bulk modulus from pressure and volume change online for pressure change MPa, volume fraction change. Small hydrostatic compression; signs must follow the stated convention. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.

How to use it

Enter pressure change MPa. Set volume fraction change. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
pressure change MPaMain input. Signed finite values. 10
volume fraction changeOption. Signed finite values. -0.001

Calculation method

bulk_modulus_GPa = -pressure_change_MPa/volume_fraction_change/1000 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply bulk modulus from pressure and volume change to the case below, keeping the displayed units and assumptions. Small hydrostatic compression; signs must follow the stated convention.

}

Choose the right tool

Choose the loading case and boundary conditions before entering values. Engineering stress differs from true stress; beam and thin-wall formulas require their stated idealizations. These calculators do not establish allowable loads or safe designs.

Limitations and common mistakes

  • Small hydrostatic compression; signs must follow the stated convention. Idealized linear material model where stated; no failure assessment, allowable stress, structural certification or compliance calculation is provided.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
