Metallic materials - Tensile testing at high strain rates - Part 1: Elastic-bar-type systems (ISO 26203-1:2018)
ISO 26203-1:2018 specifies methods for testing metallic sheet materials to determine the stress-strain characteristics at high strain rates. This document covers the use of elastic-bar-type systems.
The strain-rate range between 10−3 and 103 s−1 is considered to be the most relevant to vehicle crash events based on experimental and numerical calculations such as the finite element analysis (FEA) work for crashworthiness.
In order to evaluate the crashworthiness of a vehicle with accuracy, reliable stress-strain characterization of metallic materials at strain rates higher than 10−3 s−1 is essential.
This test method covers the strain-rate range above 102 s−1.
NOTE 1 At strain rates lower than 10−1 s−1, a quasi-static tensile testing machine that is specified in ISO 7500‑1 and ISO 6892‑1 can be applied.
NOTE 2 This testing method is also applicable to tensile test-piece geometries other than the flat test pieces considered here.
Metallische Werkstoffe - Zugversuch bei hohen Dehngeschwindigkeiten - Teil 1: Elastische Stoßwellentechnik (ISO 26203-1:2018)
Dieses Dokument legt Prüfverfahren für Bleche aus metallischen Werkstoffen fest, um Kennwerte aus dem Spannung/Dehnung-Diagramm bei Anwendung hoher Dehngeschwindigkeiten zu bestimmen. Dieses Dokument behandelt die Anwendung der Stoßwellentechnik.
Basierend auf Versuchen und Berechnungen zur Crashsicherheit, z. B. der Finite Elemente Analyse (FEA), ist für Crashtests an Fahrzeugen der Dehngeschwindigkeitsbereich zwischen 10−3 s−1 und 103 s−1 am wichtigsten.
Um eine exakte Bewertung der Crashsicherheit eines Fahrzeugs zu ermöglichen, muss das Spannungs-Dehnungs Verhalten metallischer Werkstoffe bei Dehngeschwindigkeiten über 10−3 s−1 zuverlässig charakterisiert werden.
Das hier beschriebene Prüfverfahren erfasst Dehngeschwindigkeiten oberhalb von 102 s−1.
ANMERKUNG 1 Bei Dehngeschwindigkeiten unter 10−1 s−1 kann eine quasistatische Zugprüfmaschine angewendet werden, die in ISO 7500 1 und ISO 6892 1 festgelegt ist.
ANMERKUNG 2 Dieses Prüfverfahren ist auch auf Zugproben anwendbar, die andere Maße als die hier beschriebenen Flachzugproben haben.
Matériaux métalliques - Essai de traction à vitesses de déformation élevées - Partie 1: Systèmes de type à barre élastique (ISO 26203-1:2018)
ISO 26203-1:2018 spécifie des méthodes pour les essais des tôles de matériaux métalliques en vue de déterminer les caractéristiques contrainte-déformation à vitesses de déformation élevées. Ce document couvre l'utilisation des systèmes d'essai de type à barre élastique.
La gamme de vitesses de déformation entre 10−3 s−1 et 103 s−1 est considérée être la plus pertinente pour les accidents de véhicule sur la base de calculs expérimentaux et numériques tels que le travail d'analyse par éléments finis (AEF) pour le comportement en cas d'accident.
De façon à évaluer le comportement des véhicules en cas d'accident avec précision, une caractérisation fiable des caractéristiques contrainte-déformation des matériaux métalliques à des vitesses de déformation supérieures à 10−3 s−1 est essentielle.
La présente méthode d'essai couvre la gamme de vitesses de déformation au-dessus de 102 s−1.
NOTE 1 À des vitesses de déformation inférieures à 10−1 s−1, une machine d'essai de traction quasi-statique, spécifiée dans l'ISO 7500‑1 et l'ISO 6892‑1 peut être utilisée.
NOTE 2 Cette méthode d'essai est également applicable aux géométries d'éprouvettes de traction autres que les éprouvettes plates considérées ici.
Kovinski materiali - Natezni preskus pri velikih hitrostih deformacije - 1. del: Sistem z elastičnim drogom (ISO 26203-1:2018)
Ta dokument določa metode za preskušanje kovinskih materialov v obliki plošč za določanje napetostno-deformacijskih lastnosti pri visokih stopnjah deformacije. Ta dokument zajema uporabo sistemov z elastičnim drogom.
Na podlagi eksperimentalnih in številskih izračunov, kot je analiza končnih elementov (FEA) za zagotavljanje pasivne varnosti pri trčenju, velja razpon stopnje deformacije med 10−3 in 103 s−1 za najpomembnejšega pri trčenju vozil.
Za natančno ocenjevanje pasivne varnosti pri trčenju vozila je zanesljiva opredelitev napetostno-deformacijskih lastnosti kovinskih materialov pri stopnjah deformacije nad 10−3 s−1 ključnega pomena.
Ta preskusna metoda zajema razpon stopnje deformacije nad 102 s−1.
OPOMBA 1: pri stopnjah deformacije pod 10−1 s−1 se lahko uporablja navidezno statična naprava za natezni preskus, kot jo določata standarda ISO 7500-1 in ISO 6892-1.
OPOMBA 2: ta preskusna metoda se uporablja tudi za geometrije preskusnih kosov, ki niso ploščati preskusni kosi, zajeti v tem standardu.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Tensile testing of metallic sheet materials at high strain rates is important to achieve a reliable analysis
3 −1
of vehicle crashworthiness. During a crash event, the maximum strain rate often reaches 10 s , at
which the strength of the material can be significantly higher than that under quasi-static loading
conditions. Thus, the reliability of crash simulation depends on the accuracy of the input data specifying
the strain-rate sensitivity of the materials.
Although there are several methods for high-strain rate testing, solutions for three significant problems
are required.
The first problem is the noise in the force measurement signal.
— The test force is generally detected at a measurement point on the force measurement device that is
located some distance away from the test piece.
