Abstract

This document 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^-3s^-1 and 10³s^-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^-3s^-1 is essential. This test method covers the strain-rate range above 10²s^-1. NOTE 1 At strain rates lower than 10^-1s^-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.
