CTE: coefficient of thermal expansion - Secant Method - Ansys

Choose a channel featured in the header of iMechanica: 

Hello,

 

I have to perform a thermo-mechanical simulation in Ansys WB and I have to provide the cte of a material.

I have few experience with thermo-mechanical simulation.

I have got a document with the material properties of this material; there I have the Tg (glass transition temperature)

and two coefficients: cte1 (below Tg) and cte2 (above Tg).

 

-->  How should I calculate the CTE for a temperature range (e.g. -50 < Tg < 300) ?   <---
