Abstract:Deiaminations and their further growth can reduce strength of laminates. This paper introduces the general concepts and classification of delaminations briefly. The investigative survey of delaminations is introduced through one-dimensional delaminations, two-delamina tions and delaminations in cylindrical shells. It is pointed out that the bending-stretching coupling and transverse shear have great influence on buckling load and characteristics of post-buckling of the delaminational structure. The buckling mode and ultimate load capacity of delaminational structure are different due to various kinds of materials or geometric ratio. Finally, some problems are put forward for further investigation.
Keywords:delamination  laminated structure  buckling  post-buckling  delamination growth  energy release rate  stability
