The tensile deformation is simulated in particular using a model system Al-Al2Cu in-situ composite. The calculated stress-strain curves agree well with the experiment result by Davidson et al. The initiation and growth of matrix slip deformation and the inhomogeneous distribution and variation of the stress in the specimen especially near the interface are obtained.The effect of matrix/ reinforcement interface and interlamellar spacing λ on the stress-strain behaviour of metal matrix composite are investigated. It is shown that the crystal macro-micro mechanical approach, which can provide some useful information to insight into the deformation mechanism, is very helpful to analyze and design the mechanical properties of metal matrix composite.Correspondent: WANG Mingzhang,(Department of Material Physics, University of Science and Technology Beijing, Beijing 100083) Key words:  metal matrix composite      elasto-plastic deformation      crystalline macro-micro mechanics      finite element method      Al-Al_2Cu      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I14/77 1NakamuraT,SureshS．ActaMetallMater,1993:41:16652RobertsonDD,MallS．JComposTechnolRes,1993:15:1813ChristmanT,NeedlemanA,NuttS,SureshS．MaterSciEngng,1989;107A:494BrockenbroughJR,SureshS,WieneckeHA．ActaMetallMater,1991;39:7355GunawardenaSR,JanssonS．LeckieFA．ActaMetallMater,1993;41:31576LevyA,PapazianJM．MetallTrans,1990;21A:4117AsaroRJ．ActaMetall,1979;27:4458PeirceD,AsaroRJ,NeedlemanA．ActaMetall,1983;31:19519HarrenSV,AsaroRJ．JMechPhysSolids,1989;37:191 10McHughPE,AsaroRJ,ShihCF．ActaMetallMater,1993;41:146111卫超,钱仁根,林实,肖纪美．固体力学学报,1989;10:22712卫超,钱仁根,林 实,肖纪美．金属学报,1989;26:A24813WeiC,LinS,QianRG,HsiaoJM．ActaMetallMater,1991;39,205114CantorB,ChadwickGA．JCrystalGrowth,1974:23:1215EshelmanFR,SmithJF．JApplPhys,1978:49:328416CantorB,ChadwickGA．JMaterSci,1975;10:57817HuntingtonHB．SolidStatePhys,1954;7:21418Dew-HugbesD,RobertsonWD．ActaMetall,1960;8:14719CarlsenKM,HoneycombeRWK．JInstMetals,1954─1955;83,449 20GreethamGG,HoneycombeRWK．JInstMetals,1960─1961;89,1321DavidsionCJ,SmithIO,ChadwickGA．ActaMetall,1980:28:6122MetcalfAG,Ed．．InterfacesinMetalMatrixComposites,NewYork:AcadmicPress,197423ChadwickGA．ActaMetall,1976:24:1137 [1] MA Guonan, ZHU Shize, WANG Dong, XIAO Bolv, MA Zongyi.
