The constitutive relationship can be expressed as
Note it is an incremental form of the constitutive relationship. Symbols and denote bulk and elastic modulus, respectively.
The elastic modulus is a function of stress.
with
The friction angle decreases with increasing .
The deviatoric stress is the difference between the major and minor principal stresses.
The bulk modulus is a function of .
