POROUS BULK MODULI: Define bulk moduli for soils and rocks.
This option is used to define the bulk moduli of solid grains a nd a permeating fluid such that their
compressibility can be considered in the analysis of a porous medium. The
*
POROUS BULK MODULI
option cannot be used with the porous metal plasticity material model.

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 value is
assumedtobeinfinite.
3. Temperature.
Repeat this data line as often as ne cessary to define the depend ence of the bulk moduli on temperature.
