POROUS BULK MODULI: Define bulk moduli for soils and rocks.
This option is use d to define the bulk mod uli of solid grains a nd a permea ting fluid such that their
compressibility can be cons idered in the analysis of a porous medium. The

option cannot be used with the porous metal pla sticity material model.
Product: ABAQUS/Standard
Type: Model data
Level: Model
Reference:
“Porous bulk moduli,” Section 20.7.3 of the ABAQUS Analysis User’s Manual
There are no parameters associated with this option.
Data lines to define bulk moduli:
First line:
1. Bulk modulus of solid grains. (Units of FL
−2
.) If this entry is blank or zero, this value is
assumedtobeinfinite.
2. Bulk modulus of permeating fluid. (Units of FL
−2
.) If this entry is blank or zero , this va lue is
assumedtobeinfinite.
3. Temperature.
Repeat this data line as often as ne cessary to define the dependence of the bulk moduli on temperature.
