Abstract：The temperature distribution all over the metal thin sheet in the process ofelastic-plastic deformation was evaluated by the finite element analysis.With anassumption of almost lack of variance in thermal conductivity during less deforma-tion,the results of the heat field calculated from the finite element analysis usingKelvin's equation of thermal conductivity is in better agreement with that surveyedby an infrared camera.This calculation seems to be available for the thermal effectcaused by elastic-plastic deformation. 收稿日期: 1985-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李守新 黄毅 师昌绪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I1/101 1 Williams,J.G.,Appl.Mater.Res.,4(1965) ,№ 2． 104． 2 Weichert,R.;Schoenert,K.,J.Mech.Phys.Solids,22(1974) ,127． 3 Fung,Y.C.,Foundation of Solid Mechanics,London,Prentice-Hill Inc.,1965,p.388． 4 Dunlap,R.W.;Hucke,E.E.;Ragone,D.V.,Exp.Mech.,8(1968) ,№ 4,154． 5 Huang,Y.(黄毅);Li,S.X.(李守新);Shih,C.H.(师昌绪),to be presented in Sixth Int.Conf.on Fracture,1984． 6 Nabarro,F.R.N.,Theory of Crystal Dislocation,Oxford University Press,U.S.A.,1967,p.692． 7 Tay,A.O.;Oxley,P.L.B.,Finite Element Methods in Engineering,Proc.1976 Int.Conf.on Finite Element Methods in Engineering,Australia,1976,p.42． 1-42． 21． 8 Marcal,P.V.;King,I.P.,Int.J.Mech.Sci.,9(1967) ,№ 3,143． 9 李大潜等编,有限元素法续讲,科学出版社,1979,p.191． 10 华东水利学院,弹性力学的有限元法,水利水电出版社,1978,p.88．/ No related articles found!
