DANSK DS/EN ISO 26203-1 PDF

This European Standard specifies the method for testing metallic sheet materials to determine the stress strain characteristics at high strain rate. This part of the standard covers the use of elastic bar type systems as the testing method. The strain rate range between 10-3 to 103 s-1 is considered most relevant to vehicle crash events based on experimental and numerical calculation such as Finite Elemental Analysis (FEA) work for crashworthiness. In order to evaluate the crashworthiness of vehicle with accuracy, the reliable stress-strain characterization of metallic materials at strain rates higher than 10-3 s-1is essential. This test method covers of the strain rate range above 102 s-1.
