Abstract/Summary Honeycomb sandwich specimens containing manufactured circular disbonds were loaded to failure in bending. Particular emphasis was placed on accurately identifying the occurrence of disbond buckling and growth initiation, as these two events are difficult to monitor. The test results are presented and then the methods used to identify disbond buckling and growth initiation are described. The method of identifying disbond buckling was very successful. The method of identifying growth initiation was largely successful but improvements are suggested. Finally, conclusions are presented and recommendations made regarding design and repair considerations. The study was performed to provide data against which predictive models can be validated, filling a large gap in the published literature regarding experimental results for disbonded sandwich structure.
