The silica beads volume fraction was changed from 0 to 0.63 to simulate the surfaces of icy bodies. Unconfined uniaxial compression tests were made in a cold room at the temperatures from \u221210\u00b0C to \u221225\u00b0C and the constant strain rates ranged from 2.9 \u00d7 10\u22123 to 8.5 \u00d7 10\u22127 s\u22121. We determined the rate dependent strength of the mixture written by inline equation = A \u00b7 \u03c3 max  n  from the relationship between the maximum stress, \u03c3 max, on the stress-strain curve and the applied strain rate, inline equation. At \u221210\u00b0C, the mixtures with silica volume fractions of 0.004\u20130.04 had almost the same strength with pure ice and the stress exponent, n, is about 3. On the other hands, at the silica volume fractions more than 0.15, the mixture became harder as the beads were more included, and it had the same stress exponent, about 6. This high stress exponent might be caused by crack generation. Also, we found that the A for silica volume fractions more than 0.15 was written by an exponential equation related to the silica volume fraction,  \u03c6 , A = 6.86 \u00d7 10\u22128exp(\u22126.35 \u03c6 ). Furthermore, we found that the n of  \u03c6  = 0.15 was independent of the temperature, and the brittle-ductile boundary of  \u03c6  = 0.29 and 0.63 was more than 30\u00b0C higher than that of pure ice.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/11706"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Geophysical Union"}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0094-8276", "subitem_source_identifier_type": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yasui, Minami"}], "nameIdentifiers": [{"nameIdentifier": "29872", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4fdd\u4e95, \u307f\u306a\u307f"}], "nameIdentifiers": [{"nameIdentifier": "29873", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Arakawa, Masahiko"}], "nameIdentifiers": [{"nameIdentifier": "29874", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u8352\u5ddd, \u653f\u5f66"}], "nameIdentifiers": [{"nameIdentifier": "29875", "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": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "yasui-grl-revise.pdf", "filesize": [{"value": "125.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 125400.0, "url": {"label": "yasui-grl-revise.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/9896/files/yasui-grl-revise.pdf"}, "version_id": "f16fc0ee-a237-4a9c-b709-63a5e81f3634"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Experimental study on the rate dependent strength of ice-silica mixture with silica volume fractions up to 0.63", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Experimental study on the rate dependent strength of ice-silica mixture with silica volume fractions up to 0.63"}]}, "item_type_id": "10", "owner": "1", "path": ["488/489/490"], "permalink_uri": "http://hdl.handle.net/2237/11706", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2009-05-08"}, "publish_date": "2009-05-08", "publish_status": "0", "recid": "9896", "relation": {}, "relation_version_is_last": true, "title": ["Experimental study on the rate dependent strength of ice-silica mixture with silica volume fractions up to 0.63"], "weko_shared_id": null}
