*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 viscoelasticm aterialif the *COMBINED TEST DATA option is used.

Products: ABAQUS/Standard ABAQUS/Explicit

Type: Model data

Level: Model

Using shear test data to deﬁne a viscoelastic material

Optional parameter:

SHRINF

Tospecify 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. Normalizedshear compliance .

2. Time t.

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

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.
