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...
