This option is used to define the elastic parameters for porous materials.
Product: ABAQUS/Standard
Type: Model data
Level: Model
Set this parameter equal to the number of field variable dependencies included in the definition of the parameters, in addition to temperature. If this parameter is omitted, it is assumed that the parameters depend only on temperature. See “Specifying field variable dependence” in “Material data definition,” Section 9.1.2 of the ABAQUS Analysis User's Manual, for more information.
Set SHEAR=G to define the deviatoric behavior with a constant shear modulus 
. Set SHEAR=POISSON (default) to compute the instantaneous shear modulus from the bulk modulus and Poisson's ratio. The Poisson's ratio should be given on the data lines.
First line:
Value of the logarithmic bulk modulus, 
. (Dimensionless.)
Value of the shear modulus, .
Value of the elastic tensile limit, 
. (This value cannot be negative.)
Temperature, 
.
First field variable.
Etc., up to four field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four):
Fifth field variable.
Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the dependence of the material parameters , , and on temperature and field variables.
