*TRS

*TRS
Used to define temperature-time shift for time history viscoelastic analysis.

This option can be used only in conjunction with the *VISCOELASTIC option.

In an ABAQUS/Standard analysis, viscoelasticity must be defined in the time domain by using the *VISCOELASTIC option with the TIME parameter.

Products: ABAQUS/Standard ABAQUS/Explicit

Type: Model data

DEFINITION

This parameter applies only to ABAQUS/Standard analyses. In an ABAQUS/Explicit analysis the Williams-Landell-Ferry approximation is the only available choice.

Set DEFINITION=WLF (default) to define the shift function by the Williams-Landell-Ferry approximation.

Set DEFINITION=USER to define the shift function in user subroutine UTRS.

Data line to define the shift function by the Williams-Landell-Ferry approximation:

First (and only) line:

Reference temperature, .

Calibration constant, .

To define a shift function not approximated by the WLF function:

No data lines are used with this option when DEFINITION=USER is specified. Instead, user subroutine UTRS must be used to define the shift function.
