怎么给ANSYS中模型的不同部分定义材料属性?优质解答选定需要修改材料属性的单元,然后按下述顺序找到GUI命令:preprocessor--modeling--move/modify--element--modifyAttrib在出现的对话框中选择需要修改的属性,可以修改很多属性的.选定修改材料属性的单元后,也可以使用EMODIF命令修改:EMODIF命令的使用请参考ANSYS使用帮助.用英文软件,正好可以锻炼一下E文,呵呵EMODIFEMODIF,IEL,STLOC,I1,I2,I3,I4,I5,I6,I7,I8Modifiesapreviouslydefinedelement.PREP7:ElementsMPMESTPRPRNFLEMEHDYPPEMEMFSIELModifynodesand/orattributesforelementnumberIEL.IfALL,modifyallselectedelements[ESEL].IfIEL=P,graphicalpickingisenabledandallremainingcommandfieldsareignored(validonlyintheGUI).AcomponentnamemayalsobesubstitutedforIEL.STLOCStartinglocation(n)offirstnodetobemodifiedortheattributelabel.Ifn,modifyelementnodepositionsn,n+1,etc.(n=1to20).Forexample,ifSTLOC=1,I1referstothefirstnode,I2,thesecond,etc.IfSTLOC=9,I1referstotheninthnode,I2,thetenth,etc.Attributesarealsomodifiedtothecurrentlyspecifiedvalues(use-ntomodifyonlynodesandnotattributes).Ifzero,modifyonlytheattributestothecurrentlyspecifiedvalues.IfMAT,TYPE,REAL,ESYS,orSECNUM,modifyonlythatattributetotheI1value.I1,I2,I3,...,I8Replacethepreviousnodenumbersassignedtothiselementwiththesecorrespondingvalues.A(blank)retainsthepreviousvalue(exceptintheI1field,whichresetstheSTLOCnodenumbertozero).Forattributes,replacetheexistingvaluewiththeI1value(orthedefaultifI1iszeroorblank).
