论文摘要
本文档介绍了用于数值模拟的免费切割钢50SIB8的材料表征。准静态拉伸测试以及霍普金森张力杆（SHTB）以各种应变速率和温度的测试用于推导约翰逊 - 奇克流动应力模型的参数。然后，在ABAQUS内SHTB检验的有限元模型（FEM）中对这些参数进行验证。
The present documents deals with the material characterization of the free cutting steel 50SiB8 for numerical simulations. Quasi-static tensile tests as well as Split Hopkinson Tension Bar (SHTB) tests at various strain rates and temperatures are used to deduce the parameters for a Johnson-Cook flow stress model. These parameters are then verified against the SHTB-experiments within a finite element model (FEM) of the SHTB-test within ABAQUS.
