This option is used to define absorption and exsorption behaviors of a partially saturated porous medium in the analysis of coupled wetting liquid flow and porous medium stress.
Products: Abaqus/Standard Abaqus/CAE
Type: Model data
Level: Model
Abaqus/CAE: Property module
Set LAW=LOG to define the absorption or exsorption behavior by the analytical logarithmic form.
Set LAW=TABULAR (default) to define the absorption or exsorption behavior in tabulated form.
Set TYPE=ABSORPTION (default) to define the absorption behavior.
Set TYPE=EXSORPTION to define the exsorption behavior (this must be a repeated use of the option for the same material).
Set TYPE=SCANNING to define the scanning line (this must be a repeated use of the option for the same material).
First line:
Pore pressure, , with the condition . (Units of FL–2.)
Saturation, s. This value must lie in the range .
Repeat this data line as often as necessary to define the relationship between and s from to in increasing values of s. At least two data lines must be specified.
First (and only) line:
A. This value must be positive. (Dimensionless.)
B. This value must be positive. (Units of L2F–1.)
. This value must lie in the range . The default is 0.01.
. This value must lie in the range . The default is 0.01 plus a very small positive number (since cannot be equal to ).
