Abstract

BasedonthecomplexvariablefunctionmethodandtheGreensfunctionmethod,thescatteringofSH- wavebyabi-materialinterfacecrackandacircularliningnearabi-materialinterfacein half-spacewasexploredandthecorrespondingdynamicstressconcentrationatthecircularlininginterfacewasinvestigated. Firstly,theexpressionofthescatteringwavewasproposedwhichsatisfiedthe freeboundaryconditions,andthentheGreensfunctionwasconstructed.Secondly,thecrackwas madeoutbythecrack-divisiontechnique,andaseriesofalgebraicequationsfordeterminingtheunknownforcesweredevelopedfromthecontinuityconditions. Finally,someexamplesforthedynamic stressconcentrationfactorsofthecircularelasticliningweregiven,andtheeffectsoftheinterface crack,theincidentwaveandthefreeboundaryonthedynamicstressconcentrationfactorsattheedge ofthecircularelasticinclusionwereanalyzed.Thecalculatedresultsshowthattheexistenceoftheinterfacecrackhasgreateffectsonthedynamicstressconcentrationfactorsatthecircularl ninginterface.
