Kachanov L.M. Delamination Buckling of Composite Materials

Kluwer Academic Publishers, 1988, 95 pages, ISBN 90-247-3770-2Considerable advances have been made lately in manufacturing light and high strength fiber-reinforced materials (such as graphite-epoxy and boron-epoxy composites). Due to their high specific strength, fiber-reinforced composites are widely used in thin-walled aircraft structures.
These materials work well under tension; in the zones of compression, however, delamination buckling can occur (most often, in the surface layer). This phenomenon significantly reduces resistance of structural elements to compression; growth of the delamination zone may lead to failure of the entire structure.
The problems of delamination buckling can be both linear and nonlinear (snap delamination buckling is an example of the latter).
This work is a brief introduction to the subject. A general approach to delamination buckling and some special problems are presented.Delamination Buckling
