The response of honeycomb sandwich structure todisbond damage, in a compressive stress field,has been assessed. Two types of disbond wereconsidered, those extending through the full width ofa panel (through-width) and those enclosed within thepanel boundaries (embedded). For each typeof disbond the failure process was establishedthrough four-point bend testing of 56 sandwichspecimens. For both types of disbond, failure wasfound to be governed by buckling-driven disbondgrowth and, consequently, models of buckling anddisbond growth were developed. Linear Winkler beamand plate models were used to predict disbondbuckling. Non-linear Winkler beam andplate models were then developed to predictpost-buckling behaviour and the initiation ofdisbond growth, through a fracture mechanicsanalysis. All models showed excellent correlationto test data. The models developed may be used toassess the criticality of disbond damage in sandwichstructure having thin-gauge, composite face-sheets.
