*SHEAR TEST DATA
18.13 *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.
Products: ABAQUS/Standard ABAQUS/Explicit

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.
