Trs(...)

This method creates a Trs object.

Path

Required arguments

None.

Optional arguments

definition

A SymbolicConstant specifying the definition of the shift function. Possible values are WLF, ARRHENIUS, and USER. The default value is WLF.

table

A sequence of sequences of Floats specifying the items described below. The default value is an empty sequence.

This argument is valid only when definition=WLF.

Table data

  • Reference temperature, θ0.

  • Calibration constant, C1.

  • Calibration constant, C2.

Return value

A Trs object.

Exceptions

None.

setValues(...)

This method modifies the Trs object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the Trs method.

Return value

None.

Exceptions

None.

Members

The Trs object has members with the same names and descriptions as the arguments to the Trs method.
