Stresses between Adherends with Different Curvatures

Abstract Closed form solutions are derived to predict the peel stresses developed between adherends which form a parallel bond but would have slightly different curvatures in their unbonded, stress-free states. The solutions are based on beam on elastic foundation analysis and may be applicable to a variety of geometries. Failure analysis based on a maximum stress criterion as well as a fracture mechanics approach are also provided. The possibility of using the analysis as the basis for a fracture test is also discussed.
