In this paper, experimental result of Split-Hopkinson Pressure Bar (SPHB) test of three common structural steels is reported and discussed. The three materials consist of JIS G3101 SS400, API5L Grade B, and S355JR. The material characteristics are presented in Johnson-Cook constitutive equations, and the corresponding parameters have been found through curve fitting. The results are comparable with those of literatures for other carbon steels, hence the acquired data may enrich the database of constitutive equations for various materials, especially carbon steels. The data can then be used for crashworthiness simulation in the future with the corresponding materials.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]High strain rates,Impact energy,Johnson Cook constitutive equation,Johnson-Cook,Material characteristics,Material characterizations,Split Hopkinson pressure bars,Structural steels[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Crashworthiness,High strain rate,Johnson-Cook,Material characterization,Structural steel[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is funded by LPDP (Indonesia Endowment Fund for Education), Ministry of Finance, Republic of Indonesia, and USAID under SHERA program, for which the authors express their gratitude.
