Manufacturing and impact behaviour of aeronautic overmolded grid-stiffened thermoplastic carbon plates

Finite element analysis of stiffened plates

The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine frequencies, mode shapes and buckling loads of different stiffened panels. In structural modelling, the plate and the stiffener are treated as separate finite elements where the displacement compatibility transformation takes into account the torsion – flexural coupling in the s...

Experimental and Numerical Methods to Characterize Electrical Behaviour of Carbon Fiber Composites Used in Aeronautic Industry

Aeronautic behaviour in the wasp - like spider ,

In only a few decades, A. brllennichi has colonized vast areas of continental Europe. This was most likely achieved by the ballooning of young spiderlings. Its original distribution was largely restricted to the Meditenanean. This makes A. brllennichi an interesting object for studying the proximate factors, behavioural and micrometeorologicaL which lead to this rapid mode of dispersal. After e...

Local Behavior of Discretely Stiffened Composite Plates and Cylindrical Shells

The Layerwise Shell Theory is used to model discretely stiffened laminated composite plates and cylindrical shells for stress, vibration, pre-buckling and post-buckling analyses. The layerwise theory reduces a 3-D problem to a 2-D problem by expanding the 3-D displacement field as a function of a surface-wise 2-D displacement field and a 1-D interpolation polynomial through the shell thickness....

COLLAPSE BEHAVIOUR OF PLATES UNDER THRUST

In line with the current research on the ultimate strength assessment of ship hull girders, careful understanding of the collapse behaviour of unstiffened plate elements within the ship hull girders is an important and necessary task. In this paper, the collapse behaviour of unstiffened plates under longitudinal and transverse thrust is studied by elastoplastic large deflection FEM and the char...
