P-WAVE MODULUS

In linear elasticity, the 'P-wave modulus' $M$ is one of the elastic moduli available to describe isotropic homogeneous materials.
It is defined as the ratio of axial stress to axial strain in a uniaxial strain state
:$sigma\_\{zz\}\; =\; M\; epsilon\_\{zz\}$
where all the other strains $epsilon\_\{$

★ } are zero.
This is equivalent to stating that
:$M\; =$
ho V_p^2
where $V\_P$ is the velocity of a P-wave.
