*COMBINED TEST DATA
Specify simultaneously the normalized shear and bulk compliances or relaxation moduli as functions of time.

This option can be used only in conjunction with the *VISCOELASTIC option and cannot be used if the *SHEAR TEST DATA and *VOLUMETRIC TEST DATA options are used.

Optional parameters:

SHRINF

To specify creep test data, set this parameter equal to the value of the long-term, normalized shear compliance .

To specify relaxation test data, set this parameter equal to the value of the long-term, normalized shear modulus .

The shear compliance and shear modulus are related by . The fitting procedure will use the specified value in the constraint .

VOLINF

To specify creep test data, set this parameter equal to the value of the long-term, normalized volumetric compliance .

To specify relaxation test data, set this parameter equal to the value of the long-term normalized volumetric modulus . The volumetric compliance and volumetric modulus are related by . The fitting procedure will use this value in the constraint .

Data lines to specify creep test data: 

First line:

  1. Normalized shear compliance .

  2. Normalized volumetric (bulk) compliance .

  3. Time .

Repeat the above data line as often as necessary to give the compliance-time data.

Data lines to specify relaxation test data: 

First line:

  1. Normalized shear modulus .

  2. Normalized volumetric (bulk) modulus .

  3. Time .

Repeat the above data line as often as necessary to give the modulus-time data.
