Abstract
In this paper, the bending and dynamic responses of sandwich panels with the size variation of different sandwich cores and the homogenized cores are analyzed numerically, including the hexagonal and rectangular cores, the square and rhombic cores and the circle and X-shape corrugated cores. In dependence on the ratio of the span dimensions to thickness, the laminate plate theory is also adopted for the static and dynamic analysis of sandwich panels with the homogenized cores. The computational results demonstrate the influencing rule of size variation of unit cells in the sandwich core on the bending and dynamic response of sandwich panels.
Key words: Sandwich panel -- Bending response -- Dynamic analysis -- Homogenization method -- Size effect

| What is OpenURL? |
The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
