The apparatus consists of the existing shaking table as the shear-loading device up to 3,600 kN, the main frame for holding two large rectangular prismatic specimens with a sliding area of 0.75 m2 and for applying normal stresses σn up to 1.33 MPa, and a reaction force unit holding the stationary specimen to the ground. The shaking table can produce loading rates v up to 1.0 m/s, accelerations up to 9.4 m/s2, and displacements d up to 0.44 m, using four servocontrolled actuators. We report results from eight preliminary experiments conducted with room humidity on the same gabbro specimens at v = 0.1–100 mm/s and σn = 0.66–1.33 MPa, and with d of about 0.39 m. The peak and steady-state friction coefficients were about 0.8 and 0.6, respectively, consistent with the Byerlee friction. The axial force drop or shear stress drop during an abrupt slip is linearly proportional to the amount of displacement, and the slope of this relationship determines the stiffness of the apparatus as 1.15 × 108 N/m or 153 MPa/m for the specimens we used. This low stiffness makes fault motion very unstable and the overshooting of shear stress to a negative value was recognized in some violent stick–slip events. An abrupt slip occurred in a constant rise time of 16–18 ms despite wide variation of the stress drop, and an average velocity during an abrupt slip is linearly proportional to the stress drop. The use of a large-scale shaking table has a great potential in increasing the slip rate and total displacement in biaxial friction experiments with large specimens.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Seismological Society of China", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1007/s11589-015-0113-4"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1867-8777", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Togo T", "creatorNameLang": "ja"}, {"creatorName": "Tetsuhiro Togo", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shimamoto T", "creatorNameLang": "ja"}, {"creatorName": "Toshihiko Shimamoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yamashita F", "creatorNameLang": "ja"}, {"creatorName": "Futoshi Yamashita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Fukuyama E", "creatorNameLang": "ja"}, {"creatorName": "Eiichi Fukuyama", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Mizoguchi K", "creatorNameLang": "ja"}, {"creatorName": "Kazuo Mizoguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Urata Y", "creatorNameLang": "ja"}, {"creatorName": "Yumi Urata", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Stick–slip behavior of Indian gabbro as studied using a NIED large-scale biaxial friction apparatus", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Stick–slip behavior of Indian gabbro as studied using a NIED large-scale biaxial friction apparatus", "subitem_title_language": "ja"}, {"subitem_title": "Stick–slip behavior of Indian gabbro as studied using a NIED large-scale biaxial friction apparatus", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4208", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4208", "relation": {}, "relation_version_is_last": true, "title": ["Stick–slip behavior of Indian gabbro as studied using a NIED large-scale biaxial friction apparatus"], "weko_shared_id": -1}
