The　paper　deals　with　the　analysis　of　the　T-effect　in　the　problem　of　an　interface　macrocrack　interacting　with　a　microvoid　in　the　process　zone　of　the　main　crack　tip.　With　the　aid　of　the　＇pseudo-traction-edge-dislocation＇　method.　the　interaction　problem　with　the　T-effect　under　the　remote　held　loading　conditions　can　be　reduced　to　singular　Fredholm　integral　equations　with　Hilbert　kernel.　After　solving　the　singular　integral　equations　numerically,　the　T-effect　on　the　main　crack　tip　parameters　is　analyzed　and　the　numerical　results　are　given　in　figures.
