Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems (ISO 16808:2022)
This document specifies a method for determination of the biaxial stress-strain curve of metallic sheets having a thickness below 3 mm in pure stretch forming without significant friction influence. In comparison with tensile test results, higher strain values can be achieved.
NOTE In this document, the term "biaxial stress-strain curve" is used for simplification. In principle, in the test the "biaxial true stress-true strain curve" is determined.
Metallische Werkstoffe - Blech und Band - Bestimmung der biaxialen Spannung/Dehnung-Kurve durch einen hydraulischen Tiefungsversuch mit optischen Messsystemen (ISO 16808:2022)
Dieses Dokument legt ein Verfahren zur Bestimmung der biaxialen Spannung/Dehnung-Kurve von Metallblechen mit einer Dicke unter 3 mm bei reinem Streckziehen ohne signifikanten Reibungseinfluss fest. Im Vergleich zu den Ergebnissen der Zugprüfung können höhere Formänderungswerte erreicht werden.
ANMERKUNG Der in diesem Dokument verwendete Begriff „biaxiale Spannung/Dehnung-Kurve“ wird der Einfachheit halber verwendet. Prinzipiell wird in dem Versuch die biaxiale wahre Spannung über dem Umformgrad ermittelt.
Matériaux métalliques - Tôles et bandes - Détermination de la courbe contrainte-déformation biaxiale au moyen de l'essai de gonflement hydraulique avec systèmes de mesure optiques (ISO 16808:2022)
Le présent document spécifie une méthode pour la détermination de la courbe contrainte-déformation biaxiale sur tôles métalliques d’épaisseur inférieure à 3 mm en formage en expansion pure sans influence significative des frottements. En comparaison à des résultats d’essais de traction, des valeurs plus élevées de déformation peuvent être obtenues.
NOTE Dans le présent document le terme «la courbe de contrainte-déformation biaxiale» est utilisé pour simplifier la rédaction. En principe, «la courbe biaxiale contrainte vraie-déformation vraie » est déterminé dans l’essai.
Kovinski materiali - Pločevina in trak - Ugotavljanje krivulje dvoosnega diagrama z izboklinskim preskusom optičnih merilnih sistemov (ISO 16808:2022)
Ta dokument določa metodo za ugotavljanje krivulje dvoosnega diagrama kovinskih plošč z debelino, manjšo od 3 mm, pri oblikovanju popolnega raztezanja brez pomembnih vplivov trenja. V primerjavi z rezultati nateznega preskusa je ob tem mogoče doseči večje natezne vrednosti. OPOMBA: V tem dokumentu je izraz »krivulja dvoosnega diagrama« uporabljen za poenostavitev. Načeloma je določen preskus »dejanske krivulje dvoosnega diagrama«.
