Department of Mechanical Aerospace and Nuclear Engineering, Rensselaer Polytechnic Institute, 110 8th Street, Troy, NY 12180, dvorak{at}rpi.edu A prestressing procedure for reduction of adhesive peel and shear stresses at the leading edge of a skin-flange assembly is analyzed for tensile and bending loads applied to the skin. Both an analytical solution based on the Greens functions and a finite element solution are presented for specific examples, together with design diagrams. Substantial shear and peel stress reductions are obtained with the proposed procedure.
Key Words: skin-flange assembly adhesive bonding prestress procedure design diagram
