摘要：

Composite plates can be optimized to maximize their buckling and postbuckling resistance. A simple, piece-wise uniform, stiffness tailoring concert has previously been shown to increase buckling loads and improve postbuckling performance. In the present study, this stiffness tailoring concept is further investigated to determine its usefulness in increasing the ultimate postbuckling failure load of a composite plate. A simple material model is used to describe the material behavior with damage. Various configurations of plates are examined in the finite element postbuckling analysis with progressive damage. The results show that highly tailored composite plates can have ultimate failure loads 3-5 times higher than a corresponding uniform plate. (C) 1999 Elsevier Science Ltd. All rights reserved.
