POROUS BULK MODULI

16.17

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.

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 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.
