Constitutive model for ASTM A992 steel at elevated temperature

It is essential to know the mechanical properties of structural steel at elevated temperatures, for analysis of structural response to fire or other high temperature extremes. One of the key elements for such analyses is the availability of a constitutive model for material stress-strain response. T...

Description
Summary:It is essential to know the mechanical properties of structural steel at elevated temperatures, for analysis of structural response to fire or other high temperature extremes. One of the key elements for such analyses is the availability of a constitutive model for material stress-strain response. This paper provides recommended engineering stress-strain equations for ASTM A992 steel for temperatures up to 1000°C, based on an extensive series of tests. These recommended stress-strain equations are compared with experimental data and with stress-strain equations recommended by Eurocode 3 (EC3) and by the US National Institute of Standards and Technology (NIST).
