| Abstract: | A thr ee-dimensional finite element model is brought forward for the unbonded damage of composite honeycomb sandwich structures. NAST RAN so ftw are is used to calculate the residual str ength of the structures and ther esumed str ength after r epairing. T he influence of the size of the unbonded area on the streng th lost and the influenceof the repairing quality on the str ength regain are studied. |
