The　J-integral　analysis　is　presented　for　the　interaction　problem　between　a　macro-interface　crack　and　subinterface　microcracks　parallel　to　the　former　in　the　near-tip　process　zone　in　dissimilar　anisotropic　composite　materials.　Elementary　solutions　respectively　considering　an　interface　crack　and　a　subinterface　crack　subjected　to　different　loads　are　given　from　which　the　interaction　problem　is　deduced　to　a　system　of　integral　equations　with　the　aid　of　superimposing　technique　(i.e.,　the　so　called　＇Pseudo-Traction　Method＇　abbreviated　as　PTM).　After　the　integral　equations　are　solved　numerically,　a　consistent　relation　among　three　kinds　of　the　J-integral　values　is　obtained.　They　are　induced　from　the　macro-interface　crack　tip,　the　microcracks,　and　the　remote　field,　respectively.　This　consistent　relation　of　the　J-integral　can　be　used　to　confirm　the　numerical　results　derived　by　using　whatever　kind　of　technique.　With　the　aid　of　J-integral　analysis,　the　interaction　behaviors　between　an　interface　crack　and　parallel　subinterface　cracks　are　investigated　in　detail,　and　some　special　physical　phenomena　are　obtained.
