This part of ISO 26203 covers the use of elastic bar type systems.\r\nThe strain rate range between 10-3 to 103 s-1 is considered the most relevant for vehicle accidents based on experimental and numerical calculations such as Finite Element Analysis (FEA) to determine crash resistance. .\r\nTo accurately assess the crash resistance of a vehicle, reliable characterization of stresses and strains of metallic materials at strain rates greater than 10-3 s-1 is essential.\r\nThis test method covers the strain rate range above 102 s-1.\r\nNOTE 1 At strain rates less than 10-1 s-1, a quasistatic tensile testing machine can be applied as specified in ISO 7500-1 and ISO 6892-1.\r\nNOTE 2 This test method can be applied to tensile test piece geometries other than the flat test pieces considered here.","link":"https:\/\/techlabsystems.com\/eng\/iso\/1-2-3\/iso-26203-1\/","name":"ISO 26203-1","slug":"iso-26203-1","taxonomy":"iso","parent":1395,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso\/1554","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso"}],"about":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/taxonomies\/iso"}],"up":[{"embeddable":true,"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso\/1395"}],"wp:post_type":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/product?iso=1554"},{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/normas?iso=1554"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
