One-dimensional simulation of split Hopkinson bar test using Matlab/Simulink ×÷Õß: Mao YJ (Mao, Yongjian)1, Li YL (Li, Yulong)1 ±àÕß: Jiang Y; Jun Y À´Ô´³ö°æÎï: PROCEEDINGS OF THE SECOND INTERNATIONAL CONFERENCE ON MODELLING AND SIMULATION (ICMS2009), VOL 2 ´ÔÊé: Modelling and Simulation-World Academic Union Ò³: 57-62 ³ö°æÄê: 2009 ±»ÒýƵ´Î: 0 ²Î¿¼ÎÄÏ×: 13 ÒýÖ¤¹ØÏµÍ¼ »áÒéÐÅÏ¢: 2nd International Conference on Modelling and Simulation Manchester, ENGLAND, MAY 21-22, 2009 Int Soc Modelling & Simulat; Int Soc Informat & Comput Sci; World Acad Union; Nanjing Univ; JiangNan Univ; TexEng Ltd ÕªÒª: Split Hopkinson bar (SHB) is widely used to determine dynamic properties of materials at high strain rates. It is well-known that in SHB theory there are several basic assumptions, such as uniform stress. Thus, design, analysis and data validation are significantly important to get enough accurate results. One-dimensional (I-D) simulation is such a basic approach for the purposes. But generally, the simulation needs deriving and programming by the theory of 1-D stress wave, which is a rather complicated process. This paper, for the first time, develops a brief method for 1-D simulation of SHB test using the software Matlab/Simulink. As an example, a SHB configuration is modeled and simulated, and the results agree well with theoretical analysis. The example shows our method has the features of visualization, modularization, concision and high-efficiency.
