A fibre-metal laminate is a composite of metal and fibre-reinforced prepreg layers. An example of such a material is Glare. It consists of alternating layers of aluminium and glass-fibre-reinforced prepreg. The material can be sensitive to delamination buckling, which occurs when a partially delaminated panel is subjected to a compressive force. The interaction of local buckling and extension of the delaminated zone typically results in a decrease of the residual strength and, eventually, in a collapse of the structure. This phenomenon can be observed in experimental tests, but numerical analyses are needed to obtain a better understanding of the mechanisms and the critical parameters. In this paper, some experimental observations are discussed regarding delamination buckling in Glare and, on the basis of these observations, a numerical model is constructed at a meso-mechanical level. In this approach, solidlike shell elements are used to model the individual layers. They are connected by interface elements, which are capable of modelling delamination between the layers. #

“…Although cylinder tubes may fail in multiple ways under combined axialpressure loadings (Marinucci and de Andrade, 2006;Tafreshi, 2004;Wiggenraad et al, 1996), delamination-type failure was commonly encountered in thick composite cylinders (Bai et al, 1997;Rasheed and Tassoulas, 2001;Zhao et al, 2000). Potential delamination of the cylinder such as annular delamination (Kachanov, 1988), strip-type delamination (Timoshenko and Gere, 1961) and buckling of the delamination regions were numerically investigated by Theotokoglou (Theotokoglou, 2006). In addition, Vedvik et al (Vedvik and Gustafson, 2008) analyzed filament wound thick composite pipes with metal liners subjected to progressive matrix cracking and plastic flow under axial loading.…”

There is accelerating interest in composite risers for deepwater applications. Composite risers offer much higher strength to weight ratios over metallic risers but there is less experience of their behavior in deepwater environments. A general review on current developments specific to composite risers highlighting the remaining challenges and the applications, design evolution, state-of-the-art modeling and experimental techniques is lacking. This paper provides such a review on fiber-reinforced polymer composite risers. The major issues for composite risers are addressed including the complicated combination of loads under harsh deep sea environment, the lack of long-term material degradation database for assessing the reliability of these riser systems and the need of effective numerical models to fully account for complex realistic loading configurations. The paper also highlights current gaps for design and application of composite risers in offshore technology and promising future research areas to help expand their utilization in deeper water.
