Considering the stress and displacement fields around an interface edge of an elastic and a power-law hardening materials joint, one single separable form solution of stress on the interface, %sigma_{ij}∝r^{λ-1}f_{ij}(θ)_{θ=0}, gives stress continuity where %sigma_{ij} denotes stress components, r and θ are polar coordinates, λ is the eigenvalue and f_{ij}(θ) is the angular function. However, the displacement on the interface in the power-law material is u_{i}∝r^{1+n(λ-1)}g_{i}(θ)_{θ=0},  and in the elastic material is  u_{i}∝r^{λ}h_{i}(θ)_{θ=0}, where  u_{i} is the displacement component, n is power-law hardening exponent, g_{i}(θ) and h_{i}(θ) are angular functions. Due to the dissimilarity of power of r the displacement does not become continuous. The theoretical study on singularity around an interface free edge of elastic/power-law hardening materials joint has not solved yet. This thesis solved the singular stress fields around an interface edge of elastic/elastic-plastic materials joint. The objective of this thesis is to present an iteration method to determine the stress and displacement fields around an interface edge of a joint in which materials behaves as an elastic and a power-law hardening material. J_{2}-deformation plasticity theory under plane strain condition is assumed for the power-law hardening material. Both the balance of force and the continuity of displacements are satisfied on the interface iteratively. The stress fields are found to be singular with the type of r^{λ_{i}-1} singularity from the i-th order approximation, where r is the radial distance from the interface. Due to the increase of iteration, the discrepancy of the r dependence of the fields along the interface is decreased. The power of r in the stress equation depends on the hardening exponent n.(i+1) or more singular terms exist in the i-th order approximation for n<(i+1)/i. As n is increased the absolute value of the i-th order of singularity, |λ_{i}-1| , tends to be decreased to zero when λ_{i}-1<0.\nAn asymptotic analysis for singular stress fields around an interface-edge of dissimilar power-law hardening materials joint has also been presented. Both the balance of force and the continuity of displacement are satisfied on the interface for two dissimilar power-law hardening materials joint having different power-law hardening exponent. In the higher order approximation, the nonlinear effective stress term was expanded by Taylor series. Our analyses show the order of stress singularity has a dependency with the combination of hardening exponents. Multiple stress singular terms exist for (n_{1}-n_{2})<1in the higher order approximation. The order of stress singularity has a dependency with the combination of hardening exponents, n_{1} and n_{2}.","subitem_description_type":"Abstract"}]},"item_113_description_25":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"指導教員 : 埼玉大学大学院理工学研究科人間支援・生産科学部門教授　荒居善雄","subitem_description_type":"Other"}]},"item_113_description_33":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_113_description_34":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_113_record_name_8":{"attribute_name":"書誌","attribute_value_mlt":[{"subitem_record_name":"博士論文(埼玉大学大学院理工学研究科(博士後期課程))"}]},"item_113_text_36":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"GD0000187"}]},"item_113_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科（博士後期課程）理工学専攻"}]},"item_113_text_5":{"attribute_name":"著者 所属（別言語）","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Md., Kowser Arefin","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":"2018-01-23"}],"displaytype":"detail","filename":"GD0000187.pdf","filesize":[{"value":"4.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"GD0000187.pdf","url":"https://sucra.repo.nii.ac.jp/record/10277/files/GD0000187.pdf"},"version_id":"d8ad524b-30cd-4be4-96a0-c4c4c7c19b7b"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Asymptotic Analysis of Stress Fields around Elastic/Elastic-Plastic Interface Edge of Dissimilar Materials Joints","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Asymptotic Analysis of Stress Fields around Elastic/Elastic-Plastic Interface Edge of Dissimilar Materials Joints","subitem_title_language":"en"}]},"item_type_id":"113","owner":"15","path":["502"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-12-09"},"publish_date":"2010-12-09","publish_status":"0","recid":"10277","relation_version_is_last":true,"title":["Asymptotic Analysis of Stress Fields around Elastic/Elastic-Plastic Interface Edge of Dissimilar Materials Joints"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-31T07:50:13.188579+00:00"}
