The experimentation includes the preparation of inducing an initial surface crack in the specimens and the fatigue crack growth testing using a table top axial-torsion servo-hydraulic dynamic testing machine. The numerical modeling for the fatigue crack growths was simulated by using a dual boundary element method software package. The crack growth paths and the fatigue lives for different loading cases and crack aspect ratios obtained from the experiments were shown to be in good agreements with those by the numerical simulations. The changes of the angles of the crack growth direction predicted by the numerical simulations and the fracture surface condition of the specimens are also presented and discussed.[/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]Axial-torsion loading,Crack-growth direction,Dual boundary element method,Fracture surfaces,Servo hydraulic,Solid cylinders,Surface cracks,Torsion loads[/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]Boundary element method,Combined axial-torsion load,Experiment,Fatigue crack growth,Surface crack[/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]The authors wish to thank the Ministry of Higher Education, Malaysia, through the High Impact Research Grant (UM.C/625/1/HIR/MOHE/ENG/33).[/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/s40799-016-0149-y[/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]
