It is shown that the features of collisions depend strongly on the grain radius composing planetesimals. When two planetesimals collide each other at speed about 10 m/s, they are broken into pieces of grain radius of 0.1 micrometer. Since tensile strength of a planetesimal increases inversely proportional to the grain radius, the collisional displacement is reduced with decreasing grain radius. It is found that planetesimals consisting of grains of 0.1 micrometer or smaller are not destroyed by collisions.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063352024","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"北海道大学低温科学研究所"},{"subitem_text_value":"北海道大学 大学院理学研究科"},{"subitem_text_value":"名古屋大学 理学部　地球惑星科学科"},{"subitem_text_value":"北海道大学 大学院理学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Low Temperature Science, Hokkaido University"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Science"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Department of Earth and Planetary Sciences, Faculty of Science"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"万代, 英俊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"城野, 信一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡邊, 誠一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 哲生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mandai, Hidetoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shirono, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Seiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Tetsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"小惑星衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"微惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"粒子衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"引張強度","subitem_subject_scheme":"Other"},{"subitem_subject":"多孔物質","subitem_subject_scheme":"Other"},{"subitem_subject":"衝突速度","subitem_subject_scheme":"Other"},{"subitem_subject":"状態方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"Van der Waals相互作用","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"エネルギー散逸","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid collision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetesimal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"particle collision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tensile strength","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"porous material","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impact velocity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equation of state","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Van der Waals interaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computerized simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"energy dissipation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"SPH simulation of collisions of grain aggregates","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SPH simulation of collisions of grain aggregates","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"38391","relation_version_is_last":true,"title":["SPH simulation of collisions of grain aggregates"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:41:24.031671+00:00"}
