However, the origin and propagation process of the later phases in a finite-sized small sample are very complicated with the overlap of multiple unknown reflections and conversions. In this study, we investigated the three-dimensional (3D) geometric effect of a finite-sized cylindrical sample to understand the development of these later phases. This study used 3D finite difference method simulation employing a free-surface boundary condition over a curved model surface and a realistic circular shape of the source model. The simulated waveforms and the visualized 3D wavefield in a stainless steel sample clearly demonstrated the process of multiple reflections and the conversions of the P and S waves at the side surface as well as at the top and bottom of the sample. Rayleigh wave propagation along the curved side boundary was also confirmed, and these waves dominate in the later portion of the simulated waveform with much larger amplitudes than the P and S wave reflections. The feature of the simulated waveforms showed good agreement with laboratory observed waveforms. For the simulation, an introduction of an absorbing boundary condition at the top and bottom of the sample made it possible to efficiently separate the contribution of the vertical and horizontal boundary effects in the simulated wavefield. This procedure helped to confirm the additional finding of vertically propagating multiple surface waves and their conversion at the corner of the sample. This new laboratory-scale 3D simulation enabled the appearance of a variety of geometric effects that constitute the later phases of the transmitted waves."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699995170464641","@type":"Researcher","foaf:name":[{"@value":"Nana Yoshimitsu"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995170464768","@type":"Researcher","foaf:name":[{"@value":"Takashi Furumura"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699995170464640","@type":"Researcher","foaf:name":[{"@value":"Takuto Maeda"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"09269851"}],"prism:publicationName":[{"@value":"Journal of Applied Geophysics"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2016-09","prism:volume":"132","prism:startingPage":"184","prism:endingPage":"192"},"reviewed":"false","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0926985116301768?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0926985116301768?httpAccept=text/plain"}],"createdAt":"2016-07-06","modifiedAt":"2024-06-18","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360298754825652736","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Rock Deformation Monitoring Using Monte Carlo Waveform Inversion"}]},{"@id":"https://cir.nii.ac.jp/crid/1360298755603602816","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Accurate determination of the first arrival time of elastic wave traveled through rock sample by machine learning"}]},{"@id":"https://cir.nii.ac.jp/crid/1390570543474605696","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Bridge the Gap Between Laboratory Scale to Natural Scale Using Near Fault Observations"},{"@language":"ja","@value":"破壊面近傍観測による室内岩石実験から自然地震までの橋渡し研究"},{"@language":"ja-Kana","@value":"ハカイメン キンボウ カンソク ニ ヨル シツナイ ガンセキ ジッケン カラ シゼン ジシン マデ ノ ハシワタシ ケンキュウ"}]},{"@id":"https://cir.nii.ac.jp/crid/1390845713013221888","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"室内透水試験における亀裂を有する安山岩の水飽和度と複素比抵抗および弾性波の関係"},{"@language":"en","@value":"Relationship between Complex Resistivity, Elastic Wave and Water Saturation of Cracked Andesite under Laboratory Fluid-Flow Test"},{"@language":"ja-Kana","@value":"シツナイ トウスイ シケン ニ オケル キレツ オ ユウスル アンザンガン ノ ミズ ホウワド ト フクソヒ テイコウ オヨビ ダンセイハ ノ カンケイ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051714791980357120","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"OpenSWPC : an open-source integrated parallel simulation code for modeling seismic wave propagation in 3D heterogeneous viscoelastic media"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1016/j.jappgeo.2016.07.002"},{"@type":"OPENAIRE","@value":"doi_dedup___::574074dffaa3a31a4c3f27348d0a9431"},{"@type":"CROSSREF","@value":"10.1029/2021jb021873_references_DOI_POu0f8xu22ZCGrJlKjG4cvpxrm2"},{"@type":"CROSSREF","@value":"10.1016/j.jappgeo.2022.104688_references_DOI_POu0f8xu22ZCGrJlKjG4cvpxrm2"},{"@type":"CROSSREF","@value":"10.1186/s40623-017-0687-2_references_DOI_POu0f8xu22ZCGrJlKjG4cvpxrm2"},{"@type":"CROSSREF","@value":"10.4294/zisin.2020-19_references_DOI_POu0f8xu22ZCGrJlKjG4cvpxrm2"},{"@type":"CROSSREF","@value":"10.3124/segj.71.71_references_DOI_POu0f8xu22ZCGrJlKjG4cvpxrm2"}]}
