Abstract
One dimensional delamination buckling and growth is analyzed using closed form cylindrical buckling and crack tip element analyses. A cylindrical buckling analysis is utilized to determine the strains, curvatures, deflections, forces and moments in a buckled region bounded by the laminate free surface and a near-surface delamination. These results are used as input into a linear crack tip element analysis to obtain the total energy release rate and individual mode I and mode II components. Geometric nonlinearities are accounted for through the loading on the crack tip element. Total energy release rate and fracture mode ratio as found by this new technique are shown to agree with nonlinear finite element results.
