Each university had different sets of SHPBs and data acquisition systems. The bars were made of maraging 350 (SUT), SAE 1055 (USP), stainless steel 17–4 pH (UCT), and stainless steel 304 (NTU), respectively. The bar diameters were in a range of 12.7 to 24.99 mm and the lengths of the pressure bars were from 700 mm to 2000 mm. Compressive SHPB tests have been conducted on four metals: commercially pure copper, stainless steel grade 316 (SS316), aluminium alloy 1100 and magnesium alloy. The strain signals and stress-strain curves for each material measured by four universities have been compared and discussed. The results showed that the flow stress fluctuated in a range of ± 9.9% for copper, ± 3.3% for SS316, ± 6.7% for aluminium and ± 15.6% for magnesium. Specific strain rate or final true strains were not targeted in this study. Hence the strain rates ranged from 987 to 2690 s−1, and final true strains varied from 0.12 to 0.38. This international collaboration attempts to provide evidence for the possible standardization of SHPB tests in the future.[/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]Dynamic characterization,High strain rates,International collaborations,Nanyang Technological University,Round Robin test,Split Hopkinson pressure bars,Swinburne University of Technology,University of Cape Town[/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]Dynamic characterization,High strain rate compression,Round-Robin test,Split Hopkinson pressure bar (Kolsky),Standardization[/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][/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.ijimpeng.2018.12.003[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
