摘要
介绍轨道车辆应用金属材料的静态及动态力学性能的测试,分别介绍材料的准静态测试、不同应变率下材料的动态性能曲线测试方法,并阐述基于LS-DYNA软件材料本构模型的建立方法及材料的应变率效应.
Static and dynamic mechanical properties test were carried out for metallic materials of railway vehi- cle. Methods of quasi-static test and dynamic performance with different strain rate are introduced. In addition, a method based on LS-DYNA in building constitutive model and strain-rate effect were expounded.
