Summary: We study the problem of crack of elliptical shape located between two bonded dissimilar elastic half-spaces and subjected to arbitrary loads. A solution is obtained by using the 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 ratios of semiaxes, and for half-spaces with different ratios of elastic constants. For special cases the results are compared with available exact solutions.
