Stress-strain analysis of a taper-taper adhesive-bonded joint under cylindrical bending

A model of a taper-taper adhesive-bonded joint under cylindrical bending ha s been derived using first-order laminated plate theory. Shear correction f actors were used to account for transverse shear deformation. A FORTRAN pro gram was written to integrate the resulting system of twelve simultaneous, linear, first-order differential equations with variable coefficients. The Linear Shooting Method was used to solve the model. A finite element model was developed using the COSMOS/M commercial finite element package to verif y the analytical model for a cross-ply laminate. The analytical model resul ts agreed well with the finite element models and predicted peak adhesive s tresses within about 2% of the finite element model.
