Perform time-temperature superposition analysis using Python.

Purpose

This App provides a tool for performing time-temperature superposition analysis. It helps to calculate the shift factor and generate the master curve.

Notes:

• It needs Embedded Python and mastercurve library. Other dependent libraries include numpy and pandas. 

Installation

1. Download the Time-Temperature Superposition.opx file, then drag and drop it onto the Origin workspace.
2. The App will start downloading dependent Python libraries. Wait a few minutes until the download is completed and restart Origin.

Operation

1. Activate a worksheet. Click the App icon to bring up the dialog.
2. Select XY worksheet columns for Input Data and specify Temperature by selecting a single worksheet column.
3. Once Temperature is specified, select Reference Temperature from the drop-down list
4. In Plots group, select the output plots you desire  
5. Click OK to output results and plots.
