Delamination buckling and growth of flat composite structural elements is presented with sufficient detail. The mathematical model for the phenomena are developed and solved. The emphasis of the analysis is to establish the load carrying capability damage tolerance of the delaminated structural element and to identify the most influencing structural parameters. Two important parameters have a governing influence on the behavior of the delaminated damaged element the size of the delamination and its position in the laminate, especially its distance from the surface. Depending on these two parameters, the damage tolerance of the laminate is either governed by delamination buckling or by the fracture toughness of the material delamination growth.
