各向同性弹性材料可以在图 中定义或从 [Excel] 导入随温度变化的应力-应变特性。 在杆件和面受热荷载作用时，这些材料参数将被考虑。
参照温度决定了无温度荷载作用的杆件或面的刚度。 For example, if a reference temperature of 300 °C is set, the reduced elastic modulus of this point of the temperature curve is applied to all members and surfaces.
The Options dialog section allows you to control if the Poisson's ratios that are applied to the complete temperature diagram are identical. Clear the check box to access the Poisson's Ratio table column for individual entries.
You have to select and define the Temperature/Modulus diagram on your own.
