The investigation deals with the load-transfer between two overlapping, continuously bonded, elastic sheets of different thickness and distinct material properties, under a given in-plane loading. It is shown first that the foregoing stress-analysis problem is--within the theory of generalized plane stress--reducible to an elastic-inclusion problem. This general reduction scheme is subsequently applied to the specific problem concerning the transfer of loading between two overlapping semi-infinite sheets, attached to each other along a common strip adjacent to their edges, if one of the sheets is subjected to an internal concentrated force at right angles to its boundary. The solution obtained for this problem is studied in detail with particular attention to the quantitative appraisal of the bond forces acting throughout the interior of the region of adhesion and those communicated by the edges of the two sheets under consideration.
