ABAQUS Keywords Reference Manual  

*SHEAR TEST DATA
Used to provide shear test data.

This option can be used only in conjunction with the *VISCOELASTIC option. The *SHEAR TEST DATA option cannot be used for a viscoelastic material if the *COMBINED TEST DATA option is used.

Using shear test data to define a viscoelastic material

Optional parameter:

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 .

Data lines to specify creep test data: 

First line:

  1. Normalized shear compliance . 

  2. Time t. 

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

Data lines to specify relaxation test data: 

First line:

  1. Normalized shear relaxation modulus . 

  2. Time t. 

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