    Notes: Summary Internal instability of structured materials and elements is occasionally observed and has been verified by experiments. The specific problems in this contribution treated analytically and numerically consist of internal instability phenomena of prestressed elastic materials and the so-called ‘membrane buckling’ of thin elastic plates and shells. A stability theory taking into consideration independent local rotations is outlined; this theory is then used to treat the membrane buckling of cylindrical shells and the in-plane buckling of rectangular plates. It is shown that under certain circumstances, the in-plane buckling mode may precede the out-of-plane buckling deformation. To simulate the internal stability phenomena numerically, a number of discrete models of structured materials are considered; based on these models numerical Finite Element (FE) buckling analyses are carried out, including linear analyses for the membrane buckling of a circular cylindrical shell model and the in-plane buckling analysis of a flat plate. The FE simulations effectively afford buckling loads and buckling modes.

    Description / Table of Contents: Resume On examine ici sur le plan théorique et expérimental le phénomène de flambage de tuyaux minces pressurisés sous charge axiale indirecte appliquée concentriquement par l’intermédiaire d’un piston sans friction. On a contrôlé au moyen d’extensomètres la direction de la déformation d’un échantillon de tuyau en polyvinylchloride (PVC) sous charge de compression axiale. Les mesures relevées ont été traitées par un ordinateur équipé d’un logiciel de traitement des déformations. On a pu ainsi déterminer expérimentalement le mode et la charge de flambage du système. On a utilisé plusieurs modèles théoriques pour décrire de façon analytique la stabilité du tuyau et on a identifié de la même manière le phénomène du flambage dans ce tuyau pressurisé. On a obtenu également des valeurs numériques pour la charge de flambage critique. On a établi une corrélation entre les flambages théorique et expérimental, ce qui a permis de déterminer le flambage de tuyaux pressurisés sous compression axiale indirecte, et d’établir un modèle théorique approprié pour décrire le phénomène.
    Notes: Abstract In this work, the buckling phenomenon of slender pressurized pipes under concentrically applied indirect axial force is experimentally and theoretically investigated. The axial force is applied via a frictionless piston. The deformation trend of a polyvinylchloride pipe sample under this compressive axial force is monitored by means of a number of strain gauges. The strain readings are processed by a computer equipped with strain processing software. The buckling modes as well as the buckling load of the system are thus experimentally determined. To describe the stability behaviour of the pipe analytically, several theoretical models are employed and the buckling phenomenon in such a pressurized pipe is analytically ascertained. Numerical values for the critical buckling loads are also obtained. The experimental and theoretical buckling studies are correlated. Through these correlations, the buckling of pressurized pipes under indirect axial pressure is substantiated and an appropriate theoretical model to describe the phenomenon is established.
