Stresses around a propagating finite crack having a constant velocity in an elastic layer sandwiched between two elastic half-planes are determined. The self-equilibrated system of pressure is applied to the crack surfaces. Application of the Fourier transform technique reduces the problem to that of solving dual integral equations. In order to solve the equations, the differences of the crack surface displacements are expanded in a series of functions that are equal to zero outside of the crack. The unknown coefficients in the series are solved using the Schmidt method. The stress intensity factors are calculated numerically for a crack in a layer made of epoxy resin sandwiched between two half-planes made of aluminum.
