*SHEAR TEST DATA

Used to provide shear test data.

This option can be used only in conjunction with the *FABRICVISCOELASTIC 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 parameters

SHRINF

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

To specify relaxation test data, set this parameter equal to the value of the long-term, normalized shear modulus gR⁢(∞). The shear compliance and shear modulus are related by jS⁢(∞)=1/gR⁢(∞). The fitting procedure will use the specified value in the constraint 1-∑i=1Ng¯iP=gR⁢(∞).

Data lines to specify creep test data

First line

  1. Normalized shear compliance jS⁢(t). (jS⁢(t)≥1)

  2. Time t. (t>0)

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 gR⁢(t). (0≤gR⁢(t)≤1)

  2. Time t. (t>0)

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