鉄鋼材料の相変態・焼戻しを考慮したFEM解析手法 山崎 陽介 岡村 一男 牧野 泰三 瀬羅 知暁 一般社団法人日本機械学会 日本機械学會論文集. A編 03875008 74 743 926 932 2008-07-25 The objective of the present paper is to propose a new FEM analysis method which takes the phase transformation and the tempering effect into account. We developed an algorithm in which the tempering effect, that is shrinkage and mechanical properties change, is represented by the change of carbon concentration. The proposed FEM analysis method correctly estimates the volume shrinkage phenomenon during tempering. This method is applied to the evaluation of residual stress in a steel block subjected to locally heating and its variation due to tempering. The calculate results well explain the change of residual stress due to tempering than the conventional quenching simulation code, and the advantage of the proposed method is confirmed. 2008-07-25 110006836782 AN0018742X 9592505 JPN CJP NDL NII-ELS 3 8 FEM Analysis Method with Phase Transformation and Tempering Effect YAMAZAKI Yousuke OKAMURA Kazuo MAKINO Taizo SERA Tomoaki The Japan Society of Mechanical Engineers Transactions of the Japan Society of Mechanical Engineers.
