适用范围：This International Standard specifies methods for testing metallic sheet materials to determine the stress-strain characteristics at high strain rates. This part of ISO 26203 covers the use of elastic-bar-type systems.The strain-rate range between 10-3s-1 to 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.
