A progressive damage model for E-glass/epoxy composite in ABAQUS Explicit was developed in this study to numerically predict low-velocity impact (LVI) damage and residual strength of an E-glass/epoxy composite component. Hashin-Rotem criteria were used to define laminate damage initiation, and traction-separation law was used to define the cohesive region. LVI and four-point bending after the impact (BAI) of the woven E-glass/epoxy composite plates were simulated and compared with available experimental data in the literature. Good agreement was found between finite element analysis (FEA) predictions and the experimental results, which include the impact zone shape, as well as the load-deflection response and residual bending strength from the four-point bending tests.[/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]Four point bending,Four-point bending test,Laminate damage,Load-deflection response,Low velocity impact,Progressive damage,Residual strength,Traction-separation law[/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]Bending after impact (BAI),Composite failure,Delamination,Low-velocity impact[/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 was funded by Kementrian Riset Teknolo-gi dan Pendidikan Tinggi Republik Indonesia (Developing Countries Partnerships Scholarship and Penelitian Dasar Unggulan Perguruan Tinggi), Institut Teknologi Bandung (P3MI), and Royal Academy of Engineering, UK (Newton Fund Industry-Academia Partnerships Programme).[/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/10.1007/s12206-020-0409-8[/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]
