Inspection using nondestructive Testing (NDT) has been developed based on several methods. Ultrasonic testing (UT) is one powerful method for NDT of internal railway crack. UT involves the reflection of acoustic waves to detect internal defects. However, to reach deep into the structure and reflect useful echo-signal due to internal crack, a proper configuration is still challenging. With current technology of computing power, modeling and simulation of ultrasound wave phenomena on the railway, it is possible to simulate processes of NDT using UT. Simulations are used to determine parameters of ultrasonic testing, such as parameters of probes and scan plan and also in the analysis of results. The paper describes modeling and simulation 3D ultrasound wave propagation using k-space pseudo-spectral methods. The simulation results are very useful for verifying the propagation of the ultrasonic signal in the given beam pattern of a transducer in 2D and 3D, wave propagation on the internal of the railway with the effect on an area with 3D in the railway track geometry and the signal pattern on the railway surface on the receiver.[/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]Current technology,Model and simulation,Modelling and simulations,Pseudospectral,Pseudospectral methods,Railway track,Ultrasonic signals,Ultrasound waves[/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]inspection,k-space pseudospectral,modeling and simulation,railway track,use nondestructive testing[/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]ACKNOWLEDGMENT This work is funded by the research grant from Ministry of Research, Technology and Higher Education (Indonesia) fiscal year 2018 and partly supported by USAID through Sustainable Higher Education Research Alliances (SHERA) Program – Centre for Collaborative (CCR) National Center for Sustainable Transportation Technology (NCSTT).[/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/10.1109/ICA.2019.8916739[/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]
