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 Testing the effectiveness of tough resin systems for improving structural performance of joints in GRP ships. ArchiMer Norwood, L; Caulier, C. A major concern in any composite structure is its ability to resist peel and shear loading; this becomes a more difficult problem where long delays in laminating have occurred or when dissimilar materials are joined together. In the case of mine countermeasure vessels, adhesion between stiffener and hull becomes critical when the ship is subjected to underwater shock loading. In order to reduce costs and improve the hull-stiffener bond, tough resin systems based on urethane acrylates have been developed to replace the mechanical crack-stopping system currently employed. This paper describes the benefits of urethane acrylates in the frame-hull application discussing the level of improvement over the mechanical system.
