The present study describes a semi-analytical
solution method for predicting the geometrically
nonlinear response of a bonded composite tubular
single-lap joint subjected to general loading conditions.
The transverse shear and normal stresses in the
adhesive as well as membrane stress resultants and
bending moments in the adherends are determined
using this method. The method utilizes the principle of
virtual work in conjunction with nonlinear thin-shell
theory to model the adherends and a cylindrical shear
lag model to represent the kinematics of the thin
adhesive layer between the adherends. The kinematic
boundary conditions are imposed by employing the
Lagrange multiplier method. In the solution procedure,
the displacement components for the tubular joint are
approximated in terms of non-periodic and periodic BSpline
functions in the longitudinal and circumferential
directions, respectively. The approach presented herein
represents a rapid-solution alternative to the finite
element method. The solution method was validated by
comparison against a previously considered tubular
single-lap joint. The steep variation of both peeling and
shearing stresses near the adhesive edges was
successfully captured. The applicability of the present
method was also demonstrated by considering tubular
bonded lap-joints subjected to pure bending and torsion.
