However, the distribution of incipient flaws in the targets, usually characterized by the Weibull parameters, has generally be implemented in the codes with values allowing to match the experimental outcomes. Here we follow the original method proposed by Weibull (1939) to measure these parameters for this Yakuno basalt. We obtain a value of the Weibull modulus m larger than the one obtained from simulation fits to the experimental data. The second Weibull parameter, called k, related to some characteristic strength of the material is also larger than those typically used in the simulations. However, the combination of the two parameters represented by ln(kV/m), where V is the volume of the target, has a value which is similar to the one allowing simulations to match the experiments. Future numerical simulations shall then use this new set of parameters to check that they still reproduce the experimental outcomes.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063505047","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":"神戸大学 大学院自然科学研究科"},{"subitem_text_value":"Observatoire de la Cote d'Azur"},{"subitem_text_value":"神戸大学 大学院自然科学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kobe University Graduate School of Science and Technology"},{"subitem_text_language":"en","subitem_text_value":"Observatoire de la Cote d'Azur"},{"subitem_text_language":"en","subitem_text_value":"Kobe University Graduate School of Science and Technology"}]},"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":"中村, 昭子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Michel, Patrick"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"瀬藤, 真人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Akiko M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Michel, Patrick","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Seto, Masato","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ワイブル分布","subitem_subject_scheme":"Other"},{"subitem_subject":"超高速衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"玄武岩","subitem_subject_scheme":"Other"},{"subitem_subject":"破砕","subitem_subject_scheme":"Other"},{"subitem_subject":"計算機プログラム","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"機械的性質","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"分布関数","subitem_subject_scheme":"Other"},{"subitem_subject":"引張強度","subitem_subject_scheme":"Other"},{"subitem_subject":"Weibull distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hypervelocity impact","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"basalt","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fragmentation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computer program","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical property","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"distribution function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tensile strength","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":"Weibull parameters of basalt targets used in high-velocity impact disruption experiments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Weibull parameters of basalt targets used in high-velocity impact disruption experiments","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1790","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20509","relation_version_is_last":true,"title":["Weibull parameters of basalt targets used in high-velocity impact disruption experiments"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:49:16.740499+00:00"}
