A semi-analytical method for determining the strain energy release
rate due to a prescribed interface crack in an adhesively-bonded,
single-lap composite joint subjected to axial tension is presented.
The field equations in terms of displacements within the joint are
formulated by using first-order shear deformable, laminated plate
theory together with kinematic relations and force equilibrium
conditions. The stress distributions for the adherends and adhesive
are determined after the appropriate boundary and loading
conditions are applied and the equations for the field
displacements are solved. Based on the adhesive stress
distributions, the forces at the crack tip are obtained and the
strain energy release rate of the crack is determined by using the
virtual crack closure technique (VCCT). Additionally, the test
specimen geometry from both the ASTM D3165 and D1002 test standards
are utilized during the derivation of the field equations in order
to correlate analytical models with future test results. The system
of second-order differential field equations is solved to provide
the adherend and adhesive stress response using the symbolic
computation tool, Maple 9. Finite element analyses using J-integral
as well as VCCT were performed to verify the developed analytical
model. The finite element analyses were conducted using the
commercial finite element analysis software ABAQUS. The results
determined using the analytical method correlated well with the
results from the finite element analyses.
