Abstract: | Finite element procedures for the analysis of composite structures under compressive loads (buckling and post-buckling) generally
are not deployed in books because they are still considered object of research whereas they are deemed as assessed by researchers
that focus their papers on restricted audience topics. Therefore, regarding these procedures, a gap exists in literature between
what researchers consider as well established and what has been already published. The aim of this paper is to contribute
to close this gap by providing an insight in linear and non-linear buckling analyses and in their use with composite structures.
Both modelling and analysis considerations are presented and discussed, focusing on what can be considered as best practice
when dealing with this kind of problems. Applications (to a stiffened panel and to a wing box) are provided for demonstrating
the effectiveness of the procedures presented. |
