For the later cycles, \u03c4_T increased-not always as the hole size decreased, and their relations were expressed in the \u03c4_\uff57-\u03c7 curves. The more the prestrain \u03b5, the higher the level of the curve. The bottom of the endurance limit \u03c4_\uff57 lay for the diameter ratio \u03b4/d\u22520.2?0.3. 3) The crack propagation was of Frost and Dugdale type as was also the case of the rotary bending and push-pull fatigue as well. 4) For the phenomena about the hardness, as the cycle ratio N/N_F increased, H_V increased by \u03b5\uff1d0\uff0c2\uff05 from the early cycle or after a slight decrease, and decreased by \u03b5\uff1d14\uff05 from the early cycle or after a slight increase. 5) The non-opening ratio i for N/N_F\uff1d0.6?0.7 levelled higher in the order of \u03b5\uff1d0, 2, 14\uff05", "subitem_description_type": "Abstract"}]}, "item_2_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "33076", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shigeyoshi, OIWAKE"}]}, {"nameIdentifiers": [{"nameIdentifier": "33077", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kazuo, UNO"}]}, {"nameIdentifiers": [{"nameIdentifier": "33078", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Setsuo, MIURA"}]}]}, "item_2_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u5317\u898b\u5de5\u696d\u5927\u5b66"}]}, "item_2_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u8ffd\u5206, \u91cd\u7fa9"}], "nameIdentifiers": [{"nameIdentifier": "33073", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u5b87\u91ce, \u548c\u96c4"}], "nameIdentifiers": [{"nameIdentifier": "33074", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4e09\u6d66, \u7bc0\u7537"}], "nameIdentifiers": [{"nameIdentifier": "33075", "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": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "15-2-1.pdf", "filesize": [{"value": "3.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 3400000.0, "url": {"label": "15-2-1.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/6559/files/15-2-1.pdf"}, "version_id": "86a79aae-589d-49c3-9a76-f9b73ff356cc"}]}, "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": "\u4e88\u52a0\u5de5\u3092\u4e0e\u3048\u305f\u70ad\u7d20\u92fc\u6a2a\u7a74\u6750\u306e\u75b2\u308c\u6319\u52d5* -\u4e88\u5f15\u5f35\u6750\u306e\u306d\u3058\u308a\u75b2\u308c\u306e\u5834\u5408-\u3000", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u4e88\u52a0\u5de5\u3092\u4e0e\u3048\u305f\u70ad\u7d20\u92fc\u6a2a\u7a74\u6750\u306e\u75b2\u308c\u6319\u52d5* -\u4e88\u5f15\u5f35\u6750\u306e\u306d\u3058\u308a\u75b2\u308c\u306e\u5834\u5408-\u3000"}]}, "item_type_id": "2", "owner": "1", "path": ["7/15/36"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/6559", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2007-04-09"}, "publish_date": "2007-04-09", "publish_status": "0", "recid": "6559", "relation": {}, "relation_version_is_last": true, "title": ["\u4e88\u52a0\u5de5\u3092\u4e0e\u3048\u305f\u70ad\u7d20\u92fc\u6a2a\u7a74\u6750\u306e\u75b2\u308c\u6319\u52d5* -\u4e88\u5f15\u5f35\u6750\u306e\u306d\u3058\u308a\u75b2\u308c\u306e\u5834\u5408-\u3000"], "weko_shared_id": 3}
