Structural steel ASTM A709—behavior at uniaxial tests conducted at lowered and elevated temperatures, short-time creep response, and fracture toughness calculation / Josip Brnic in Journal of engineering mechanics, Vol. 136 N° 9 (Septembre 2010)  

Public ISBD [article]  inJournal of engineering mechanics > Vol. 136 N° 9 (Septembre 2010) . - pp. 1083-1089 Titre : Structural steel ASTM A709—behavior at uniaxial tests conducted at lowered and elevated temperatures, short-time creep response, and fracture toughness calculation Type de document : texte imprimé Auteurs : Josip Brnic, Auteur ; Marko Canadija, Auteur ; Goran Turkalj, Auteur Article en page(s) : pp. 1083-1089 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Structural steel Material properties Temperature effects Creep Tests. Résumé : This paper presents the temperature dependence of the mechanical properties of structural high-strength low-alloy (HSLA) ASTM A709 Gr50 steel (En10025: S355 JO; DIN: ST 52-3U). Engineering stress-strain diagrams at lowered and elevated temperatures are presented. Creep responses for selected constant stresses at selected temperatures are also presented and are fit with a rheological model. Additionally, a relation between impact toughness and fracture toughness is proposed and is validated using results from notch impact tests on a Charpy pendulum impact machine.
