The interaction between two inclined cracks subjected to remote tension lying in the upper half of bonded dissimilar materials is considered. The hypersingular integral equation for the problem is formulated using the complex variable function method with the crack opening displacement function as the unknown and the tractions along the crack as the right-hand term. The appropriate quadrature formulas are applied in solving the hypersingular integral equation for the unknown function. Numerical results showed that the nondimensional stress intensity factor depends on the position of the cracks and the elastic constants ratio
