EN ISO 16808:2014

Metallic materials - Sheet and strip - Determination of biaxial stress-strain curve by means of bulge test with optical measuring systems (ISO 16808:2014)

ISO 16808:2014 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.

Metallische Werkstoffe - Blech und Band - Bestimmung der biaxialen Spannung/Dehnung-Kurve durch einen hydraulischen Tiefungsversuch mit optischen Messsystemen (ISO 16808:2014)

Diese Internationale Norm legt ein Verfahren zur Ermittlung 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 der Norm verwendete Terminus „biaxialen Spannung/Dehnung-Kurve“ ist 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 16808:2014)

L'ISO 16808:2014 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 la déformation peuvent être obtenues.

Kovinski materiali - Pločevina in trak - Ugotavljanje krivulje dvoosnega diagrama z izboklinskim preskusom optičnih merilnih sistemov (ISO 16808:2014)

Standard EN ISO 16808 določa metodo za ugotavljanje krivulje dvoosnega diagrama kovinskih pločevin 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.
