Thermal-Mechanical Analysis Applications Package

Here you find the Thermal-Mechanical analysis applications modules for for advanced data analysis of the Coefficient of Thermal Expansion (CTE), Glass Transition Temperature (Tg), and Warpage Analysis:

CTE Analysis Package

  • Create a GUI for CTE analysis based on Istra4D exported data with:
  • Two temperature selection methods: stable temperature stages method and temperature scanning range method.
  • Two evaluation methods: line gauge elements and VSG (virtual strain gauge) based methods for standard CTE values and CTE distribution analysis.
  • Save plot diagrams in .png and evaluation results as .csv data files.

CTE Calculation – One Line

  • Create a GUI to determine CTE values based on selected temperature values and Line Eng. Strain value from one line gauge element defined in Istra4D.
  • Determine glass transition temperature (Tg) based on two selected CTE values.
  • Save plot diagrams and evaluation results in .png and .csv format.

CTE Calculation – One Polygon

  • Create a GUI to determine CTE values based on selected temperature values and Mean over surface value of Eng. Principal Strain 1 and 2 from one polygon element defined in Istra4D.
  • Determine glass transition temperature (Tg) based on two selected CTE values.
  • Save plot diagrams and evaluation results in .png and .csv format.

CTE Curve Calculation – One Line

  • Create a GUI to determine CTE vs. Temperature curve based on the Line Eng. Strain value of one line gauge element with a user defined scanning window size and scanning area for CTE evaluation process.
  • Save plot diagrams and evaluation results in .png and .csv format.

CTE Distribution Analysis

  • Create a GUI for full-field CTE distribution analysis based on selected temperature values.
  • Save plot diagrams and evaluation results in .png and .csv format.
