BS EN ISO 26203-1:2018规定了测试金属板材的方法，以确定高应变率下的应力应变特性。本文件涉及弹性杆式系统的使用。基于实验和数值计算，如耐撞性有限元分析（FEA）工作，认为10-3和103 s-1之间的应变率范围与车辆碰撞事件最相关。为了准确评估车辆的耐撞性，必须在高于10-3 s-1的应变率下对金属材料进行可靠的应力-应变表征。交叉引用:ISO 6892-1:2016ISO 26203-2ASTM E1875JIS Z 2280JIS Z 8807ISO 7500-1购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN 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.Cross References:ISO 6892-1:2016ISO 26203-2ASTM E1875JIS Z 2280JIS Z 8807ISO 7500-1All current amendments available at time of purchase are included with the purchase of this document.
