✦ Synopsis

The problem of a finite line bond between two dissimilar infinite strips is considered in this paper. Integral transforms are used to reduce the problem to a system of singular integral equations of the second kind. The numerical results for various geometries and material combinations are obtained by using an appropriate numerical quadrature scheme. It is found that the normal stress intensity factor for layers of identical materials is positive if the load acts on the thicker layer, and negative if the load acts on the thinner layer. For various combinations of different materials, the normal stress intensity factor can be positive or negative for different thicknesses of the layers. For thin layers, the Poisson's ratios have an important effect on the stress intensity factor.
