COURBE DE WOHLER PDF

Sandwich panels have a very high stiffness to weight ratio, which makes them particularly useful in the aerospace, marine and in almost in all the industrial applications. However, traditional sandwich structures present problems like their tendency towards delamination, interfacial debonding and other complicated modes of failures. The aim of the present study is to investigate the mechanical behaviour of sandwich composite materials under dynamic loading. They consist of epoxy resin and glass fibres for the skins and PVC foam of various densities for the core. These tests were carried out under displacement control at various displacement levels. Stiffness degradation is used to study the mechanical behaviour of sandwich composites in fatigue.

Dans un but de reduction de poids des avions, un alliage Al-Cu-Li T8 assemble par friction-malaxage est envisage par les avionneurs pour des applications de type fuselage et intrados de l'aile. L'objectif de cette etude est de determiner le comportement en fatigue des soudures par friction-malaxage et l'influence de certains defauts de soudage pour une duree de vie de l'ordre de cycles.
