bulk modulus

The bulk modulus tells how "stiff" the material is.

The effective bulk modulus and density near the static limit are positive as predicted.

A perfect gas can sustain no shear forces so that the above bulk modulus is the only relevant one.

For consistency with linear elasticity, we must have where is the bulk modulus.

The bulk modulus of a material is a measure of its resistance to uniform pressure.

For a fluid, only the bulk modulus is meaningful.

When the gas is not ideal, these equations give only an approximation of the bulk modulus.

It is possible to measure the bulk modulus using powder diffraction under applied pressure.

The restoring force, which acts to return the medium to its original position, is provided by the medium's bulk modulus.

The speed is determined by the water's bulk modulus and mass density.
