We adopt a non-linear elastic-plastic model, which is more realistic than the plastic-rigid model used in previous works. We found that the peak stress attenuates rapidly in the region where the stress becomes comparable to the material strength. This is considerably different from the previous estimate which claims the attenuation becomes slow there as in the case of ideal gas. The rapid attenuation is due to double shock and rarefaction structure, which is characteristic to elastic-plastic material, and the attenuation rate is almost independent of material parameters.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063352026","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":"東京大学 理学部　地球惑星科学科"},{"subitem_text_value":"東京工業大学 理学部　地球惑星科学科"},{"subitem_text_value":"名古屋大学 理学部　地球惑星科学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo Department of Earth and Planetary Sciences, Faculty of Science"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology Department of Earth and Planetary Sciences, Faculty of Science"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Department of Earth and Planetary Sciences, Faculty 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":"三谷, 典子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井田, 茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡邊, 誠一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mitani, Noriko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ida, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Seiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超高速衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"微惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波減衰","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波伝播","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波干渉","subitem_subject_scheme":"Other"},{"subitem_subject":"弾性波","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"hypervelocity impact","subitem_subject_language":"en","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":"shock wave attenuation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shock wave propagation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shock wave interaction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"elastic wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computerized simulation","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":"Numerical simulation of shock attenuation in solids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical simulation of shock attenuation in solids","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":"38393","relation_version_is_last":true,"title":["Numerical simulation of shock attenuation in solids"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:41:22.457238+00:00"}
