The problem of crack of elliptical shape located between two bonded dissimilar elastic half spaces and subjected to arbitrary loads is considered. A solution is obtained by using corresponding traction boundary pseudodifferential equations. Resulting equations are then solved by means of an analytical-numerical method. Strain energy release rates along the crack contours are presented for elliptical cracks with different rations of semiaxes, and for half spaces with different rations of elastic constants. Forspecial cases the results are compared with the available exact solutions
