The cracks are in the opening mode and not interacting with any stress waves. A pulsed holographic optical system records and reconstructs a crack front observed through a side boundary of a specimen, and the reconstructed image is photographed. A method is developed to decrease an aberration introduced by inhomogeneity of refractive index in PMMA, where the inhomogenity results from manufacturing process of the PMMA. Also discussed are effects of changes of specimen thickness and refractive index in the strong stress field near a crack tip. From an obtained photograph one can know the shape of a crack front, which is not always symmetric. One can moreover measure the two angles between the crack front and the two specimen surfaces. The angles are important quantities to understand the three-dimensional structure of the stress field around the crack tip. The measured angles are similar to the numerical results given by Bazant and Estenssoro.", "subitem_description_type": "Abstract"}]}, "item_10001_description_6": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "・rights：日本機械学会\n・rights：本文データは学協会の許諾に基づきCiNiiから複製したものである\n・relation：isVersionOf：http://ci.nii.ac.jp/naid/110002373097/\n\n", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "一般社団法人日本機械学会"}]}, "item_10001_relation_17": {"attribute_name": "関連サイト", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "CiNii"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110002373097/", "subitem_relation_type_select": "URI"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03875008", "subitem_source_identifier_type": "ISSN"}]}, "item_10001_version_type_20": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "鈴木, 新一"}], "nameIdentifiers": [{"nameIdentifier": "2299", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000060135415", "nameIdentifierScheme": "NRID"}, {"nameIdentifier": "60135415", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://kaken.nii.ac.jp/ja/search/?qm=60135415"}]}, {"creatorNames": [{"creatorName": "吉山, 育伸"}], "nameIdentifiers": [{"nameIdentifier": "2752", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SUZUKI, Shinichi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "2753", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YOSHIYAMA, Ikunobu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "2754", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2013-07-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "n03875008-0056-1107.pdf", "filesize": [{"value": "681.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_11", "mimetype": "application/pdf", "size": 681300.0, "url": {"label": "n03875008-0056-1107", "url": "https://repo.lib.tut.ac.jp/record/1239/files/n03875008-0056-1107.pdf"}, "version_id": "2cd57c5f-120a-47d0-822a-114811438bbd"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Fracture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Measurement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Optical_Engineering", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Holography", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Crack_Front", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic_Fracture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Three-dimensional_Stress_Field", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Fracture", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Measurement", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Optical_Engineering", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Holography", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Crack_Front", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic_Fracture", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Three-dimensional_Stress_Field", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "高速進展き裂前縁のホログラフィ撮影", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "高速進展き裂前縁のホログラフィ撮影"}, {"subitem_title": "Pulsed Holography for Photographing Fast Propagating Crack Fronts", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "24", "path": ["9"], "permalink_uri": "https://repo.lib.tut.ac.jp/records/1239", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-07-22"}, "publish_date": "2013-07-22", "publish_status": "0", "recid": "1239", "relation": {}, "relation_version_is_last": true, "title": ["高速進展き裂前縁のホログラフィ撮影"], "weko_shared_id": -1}
