Última Durabilité d'assemblages métal/élastomère en milieu marin ArchiMer Tchalla, Siwavi Tatiana. In some industrial applications, bonding rubber coatings to metallic pipelines is a suitable solution to protect them from marine corrosion. This study deals with the long term behavior of such metallic coated pipelines in a marine environment. Two different approaches have been developed. The first focuses on degradation data of pipelines used for around thirty years in normal service conditions. As these bonded assemblies are different in terms of material formulations, manufacturing processes and aging conditions, statistical tools were used to identify homogeneous groups with identical aging mechanisms. Also, based on these results, the main degradation mechanisms of the rubber coating were established. The second approach focused on pipelines used...

Y.; Davies, Peter; Le Gac, Pierre-yves. The objective of the study is to identify the 3D behaviour of an adhesive in an assembly, and to take into account the effect of ageing in a marine environment. To that end, three different tests were employed. Gravimetric analyses were used to determine the water diffusion kinetics in the adhesive. Bulk tensile tests were performed to highlight the effects of humid ageing on the adhesive behaviour. Modified Arcan tests were performed for several ageing times to obtain the experimental database which was necessary to identify constitutive models. A Mahnken-Schlimmer type model was determined for the unaged state according to a procedure developed in a previous study. This identification used inverse techniques. It was based on the unaged modified Arcan... Tipo: Text Palavras-chave: Water resistance; Arcan test; Ageing; Epoxides; Finite-element stress analysis; Durability.
