Abstract：The strain energy partitioning(SEP)approach,namely,a modification ofstrain-range partitioning(SRP),has been developed to predict the creep fatiguecrack initiation life for GH33A Ni-base superalloy at 700℃ and 1Cr18Ni9Ti stain-less steel at 600℃.It shows that the life can be predicted by two variables:themaximum tensile stress and the partitioned inelastic strain-range,i.e.,the strain-range component in SRP is substituted by the strain energy component in SEP.The low-cycle fatigue data at elevated temperature for these two given alloys arecorrelated and predicted to within a factor of 2 using SEP,while some numeralsof data for GH33A beyond the factor of 2 using SRP.In addition,the predica-bility of SEP versus SRP has been evaluated by 8 other alloys of high-strengthand low-ductility.It would seem that SEP is an improvement over SRP. 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 何晋瑞 段作祥 宁有连 赵迪 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I1/54 1 Manson,S.S.,Advances in Creep Structures,Eds.Smith,A.I.;Nichlson,A.M.,Applied Science Publishers,London,1971,p.229． 2 Manson,S.S.,Int.J.Fract.Mech.,2(1966) ,№ 1,32． 3 Halford,G.R.;Manson,S.S.,ASM Trans.Q.,61(1968) ,№ 1,94． 4 Berling,J.T.;Coway,J.B.,Metall.Trans.,1(1970) ,600． 5 Snaeb,R.E.;Bui-Quoc,T.,Creep and Fatigue in Elevated-Temperatures Applications,Pro.Int.Conf.,IME-ASME-ASTM,Vol.1,Mechanical Engineering Publishers,London,1973,p.186． 6 Manson,S.S.,NASA TM X-67838,1971,p.1． 7 Coffin,L.F.Jr.,Symp.on Creep-Fatigue Interaction,Ed.Curran,R.M.,Metal Properties Council,New York,1976,p.349． 8 Ostergren,W.J.,ASTM Standardization News,4(1976) ,327． 9 Majumdar,S.;Maiya,P.S.,ANL-76-58,1976,p.1． 10 何晋瑞,未发表资料,1980． 11 宁友连,段作祥,第一届高温疲劳及高温应变测试技术讨论会论文摘要汇编,卷1,中国航空学会理化测试学组,成都,1982,p.148． 12 段作祥;宁友连,ibid.,卷1,1982 p.132． 13 Berstein,H.L.,AFML TR-79-4075,1979． 14 Manson,S.S.,AGARD CP-243,1978． 15 Hyzak,J.M.;Berstein,H.L.,AGARD CP-243,1978,p.5． 16 Halford,G.R.;Nachtigall,A.J.,15th Joint Propulsion Conf.,AIAA/SAE/ASME,1979,U.S.,p.10． No related articles found!
