Effects of foam joints on the flexural wrinkling strength of sandwich panels

Mahendran, Mahen & McAndrew, Duncan C. (2001) Effects of foam joints on the flexural wrinkling strength of sandwich panels. International Journal of Steel Structures, 1(2), pp. 105-112.


In Australia, sandwich panels are commonly made of steel faces and expanded polystyrene foam cores. Flexural wrinkling is often the governing criterion in the design of these panels. The presence of joints between the polystyrene foam slabs in the transverse direction introduces a reduction to the flexural wrinkling stress of the panel. Therefore a series of full scale experiments and finite element analyses were conducted to evaluate the effects of transverse joints on the flexural wrinkling stress of sandwich panels with flat steel faces subjected to a lateral pressure loading. The results showed that the presence of transverse joints caused a significant reduction to wrinkling strength. This paper presents the details of this investigation, the results and comparison with available theoretical and design solutions.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
