The paper deals with post-buckling experimental investigation on stiffened composite panels with pre-damage. Two panels with four equally spaced stiffeners were manufactured and tested. The damage was implemented at the vulnerable stiffener edge. Attempts were made to obtain the buckling load, ultimate carrying capacity and other wanted structure properties. A numerical methodology for the post-buckling...
This paper develops a multiscale eigenelement method based on multilevel substructure technology for the multiscale analysis of periodical composite structures, and provides a comparison study with user point of view for the multiscale methods including the mathematical homogenization method, the heterogeneous multiscale method, the multiscale finite element method and the generalized finite element...
