Risposta:
Le proprietà di tensioni-deformazioni dipendenti dalla temperatura di un materiale isotropo elastico possono essere definite in un diagramma o importate da [Excel]. Queste proprietà sono considerate per le aste e gli elementi di superficie soggetti a carico termico (variazioni o differenze di temperatura).
The Reference temperature defines stiffnesses for the members or surfaces that have no temperature loads. 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.
