Última Correlation essais-calcul pour materiaux composites en application marine ArchiMer Choqueuse, Dominique; Davies, Peter; Bigourdan, Benoit. The use of finite element calculations is valuable in the design of composite structures, but few examples of correlations between measured behaviour and finite element calculations are currently available. After definition of a representative type of structure (a stiffened sandwich boat hull), and construction of a test set-up allowing the loading of such panels (uniform pressure loading of 1 m by 2 m panels), modelling was performed in four laboratories using different finite element codes. The results obtained (deflections and strains) have been correlated with test results. A satisfactory correlation is obtained for deflections (differences around 20% for the central deflection) but the correlation between measured and calculated strains is less...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1046.pdf Essai de caractérisation sous pression de panneaux en composites pour structures marines ArchiMer Reichard, R. Traditional testing of FRP sandwich panels using uniaxial loading provides useful data for structural designers, but these tests do not work well for multiaxially reinforced laminates or for sandwich laminates. Sandwich laminates are generally used to increase the flexural properties of a panel. Flexural testing of sandwich beams does not address panel membrane effects, which can be significant. As a result, a number of different methods have been developed for testing panels. Experiments with multiaxial FRP sandwich panels have been conducted to evaluate the behavior of panel laminates with various fiber orientations and core materials under both static pressure loading and hydrodynamic shock loading. The test apparatus and methods are described, and the...
