Abstract：Based on the Hart's differential constitutive equation,an attempt was made toderive an expression for the correlation among m-n-δ including the effects of boththe strain hardening,n,and strain-rate sensitivity,m,as follow:(?)and the simplified form:(?)It was found that this expression is in agreement with the current analysis of them-δ relations given by Ghosh and Ayres,or with the classical analysis by Con-sidère while n=0 or m=0 respectively.The calculated results of abovementionedexpression in contrast to experiments are coincidence. 收稿日期: 1985-02-18      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 连建设 张吉人 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1985/V21/I2/118 1 Backofen,W.A.;Turner,I.R.;Avery,D.H.,ASM Trans.Q.,57(1964) ,980． 2 Hart,E.W.,Acta Metall.,15(1967) ,351． 3 Woodford,D.A.,ASM Trans.Q.,62(1969) ,291． 4 Morrison,W.B.,Trans.Metall.Soc.AIME,242(1968) ,2221． 5 Avery,D.H.;Stuart,J.M.,14th Sagamove Army Materials Research Conf.Raquette Lake,N.Y.1967． 6 Ghosh,A.K.;Ayers,R.A.,Metall.Trans.,A7(1976) ,1589． 7 Hutchinson,J.W.;Neale,K.W.,Acta Metall.,25(1977) ,839． 8 Ghosh,A.K.,Acta Metall.,25(1977) ,1413． 9 Nichols,F.A.,Acta Metall,28(1980) ,663． 10 连建设,机械工程学报,18(1982) ,№4,21． 11 Lin.I.H.;Hirth,J.P.;Hart,E.W.,Acta Metall,29(1981) ,819． 12 Considère,A.,Ann.Ponts Chaussees,6(1885) ,574． 13 Hart,E.W.,Acta Metall.,18(1970) ,599． 14 Ferron,G.;Mliha-Touati,M.,Scr.Metall.,16(1982) ,911． No related articles found!
