*POROUS ELASTIC
2. Etc.,up to eight field variables per line.
Repeat this set of data lines as oftenas necessar y to define the dependence of themater ialparameters
,G, and on temperature and field variables.
Data lines to define the instantaneousshear modulus from the bulk modulus and Poisson’s ratio:
First line:
1. Valueof the logarithmic bulk modulus, . (Dimensionless.)
2. Value of Poisson’s ratio, .
3. Valueof the elastic tensile limit, . (This value cannot be negative.)
4. Temperature, .
5. Firstfield variable.
6. Etc., up to four field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater thanfour):
1. Fifthfield variable.
2. Etc.,up to eight field variables per line.
Repeat this set of data lines as oftenas necessar y to define the dependence of themater ialparameters
,, and on temperature and field variables.
