A quantity δ(τ) is defined to be the thermal layer, which is analogous to the boundary layer in a viscous flow. The concept, proposed by T. R. Goodman, is conveniently used for the approximate analysis of heat conduction problems in connection with his Heat-Balance Integral analogous to the Momentum Integral. This paper presents the theoretical foundation for the concept of the thermal layer, first by its analogy to the boundary layer, and secondly by describing the heat conduction process as the stochastic process of the Brownian motion of the particles, the process is mathematically equivalent to the Fourier's law of heat conduction. Then the general method of thermal layer approximation is presented, and is used for the analysis of heat conduction problems of a slab, a cylinder and a insulation coating. These solution is then used for the analysis of thermo-elastic problems such as thermal stresses, thermal shock, thermally induced vibration and deflection problems. Easiness of the analysis together with an explicit character of the solution suggest the wide applicability of the method in these field.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4135032000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8097","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162214","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三浦, 公亮"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIURA, Koryo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA4135032.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4135032.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35150/files/SA4135032.pdf"},"version_id":"b07c8793-0300-4fba-927f-eec95c58f881"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"熱層近似の方法 : 熱伝導・熱弾性問題の近似解法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"熱層近似の方法 : 熱伝導・熱弾性問題の近似解法"}]},"item_type_id":"9","owner":"1","path":["1890","1909"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35150","relation_version_is_last":true,"title":["熱層近似の方法 : 熱伝導・熱弾性問題の近似解法"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:25:41.916135+00:00"}
