Abstract:

Results of the analyses of stresses, strains and displacements in both the adhesive bond and the adherends of bonded composite material structures and bonded metallic structures are presented. Joint configurations include the single lap, the double lap, the single doubler, the double doubler, and the stepped lap joint. The methods will be useful in designing and analyzing such joints under static, dynamic and thermal loads, as well as accounting for stresses incurred during fabrication as well as hygrothermal histories. Also shown are the effects of important geometric and material parameters on the stress, strain and displacement distributions. Author
