TREATMENT OF UNSYMMETRIC ADHESIVELY BONDED COMPOSITE SANDWICH PANELS-TO-FLANGE JOINTS

This paper presents an analytical solution for determination of stresses in unsymmetric adhesively bonded joints. The classical sandwich plate theory and an adhesive interface constitutive model are employed for this development. An analytical solution is also developed for the consideration of the effect of fracture in the joints, using the modified crack closure. Joints with various configurations (symmetrical and/or unsymmetrical, single skin and/or sandwich composites), and joints having different thickness, length, and lay up, including the effect of crack tip position, can be treated with these solutions. Finite element analysis (FEA) is used to confirm the integrity of these solutions. Results from the proposed solution agree well with the results obtained from FEA.
