"subitem_description_type": "Abstract"}, {"subitem_description": "The dynamic Finite Element Method is frequently used in analyzing wave propagation problems. In the case of infinite media or infinite half space, the presence of artificial boundaries introduces wave reflections from boundaries. The problem can be overcome by constructing a model of sufficient size that the required solution is obtained before the reflections arrive. But this is not always available, because the model size is limited by a computer storage. Lysmer et al (1969) developed a model system of dashpots at boundaries and transmitting boundary method as non-reflecting boundary. Their methods have some approximation, for example, basement layer is rigid and so on. Authors tried to solve the problem applying the Smith-Cundall\u0027s method and extended the method to the three dimensional problem. The Smith-Cundall\u0027s method is to solve the problem by superposing two types of reflected waves from Dirichlet\u0027s and Neumann\u0027s boundaries. This method is theoretically complete. The authors made clear the weak point of the method, but the influence of the weak point on the computed results is small. Therefore, the results by this method are reliable. This method treats problems in time domain, so non-linear problems will be solved by this method in the near future.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "128385", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Takanobu"}]}, {"nameIdentifiers": [{"nameIdentifier": "128386", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hakuno, Motohiko"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000032924", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162258", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00408972", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u65e5\u672c\u96fb\u4fe1\u96fb\u8a71\u516c\u793e"}, {"subitem_text_value": "\u5730\u9707\u7814\u7a76\u6240"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u9234\u6728, \u5d07\u4f38"}], "nameIdentifiers": [{"nameIdentifier": "128383", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4f2f\u91ce, \u5143\u5f66"}], "nameIdentifiers": [{"nameIdentifier": "128384", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ji0592006.pdf", "filesize": [{"value": "1.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1700000.0, "url": {"label": "ji0592006.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/32924/files/ji0592006.pdf"}, "version_id": "87e3d997-daaf-4e05-b15e-0dec5741bfd1"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u6d88\u6ce2\u5883\u754c\u3092\u6301\u3063\u305f\u6709\u9650\u8981\u7d20\u6cd5\u306b\u3088\u308b\u6ce2\u52d5\u4f1d\u64ad\u89e3\u6790", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u6d88\u6ce2\u5883\u754c\u3092\u6301\u3063\u305f\u6709\u9650\u8981\u7d20\u6cd5\u306b\u3088\u308b\u6ce2\u52d5\u4f1d\u64ad\u89e3\u6790", "subitem_title_language": "ja"}]}, "item_type_id": "4", "owner": "1", "path": ["80/4535/4787/4793", "9/504/4538/4789/4794"], "permalink_uri": "https://doi.org/10.15083/0000032924", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-05-30"}, "publish_date": "2008-05-30", "publish_status": "0", "recid": "32924", "relation": {}, "relation_version_is_last": true, "title": ["\u6d88\u6ce2\u5883\u754c\u3092\u6301\u3063\u305f\u6709\u9650\u8981\u7d20\u6cd5\u306b\u3088\u308b\u6ce2\u52d5\u4f1d\u64ad\u89e3\u6790"], "weko_shared_id": -1}
