Porous Bulk Moduli

The porous bulk moduli:

  • must be defined whenever the compressibility of the solid grains or the compressibility of the permeating fluid is to be considered in the analysis of a porous medium; and

  • must be defined when a swelling gel is modeled (Moisture Swelling).

Defining Porous Bulk Moduli

You can specify the bulk modulus of the solid grains and the bulk modulus of the fluid as functions of temperature. If either modulus is omitted or set to zero, that phase of the material is assumed to be fully incompressible.

Specifying Field Variable Dependence for the Porous Bulk Moduli

The porous bulk moduli can be defined as functions of field variables. You must specify the number of user-defined field variables required.

Abaqus/CAE Usage

Specifying field variable dependence for the porous bulk moduli is not supported in Abaqus/CAE.
