Elastic wave propagation in solids can be controlled and manipulated by properly designed metamaterials. In particular, polarization conversion can be obtained by using anisotropic materials. In this paper, we propose a three-component locally resona

International audience; In the present work, an optimization method is proposed in order to produce innovative stiffening layouts for large stiffened cylindrical shell structures, as they appear in the aerospace industry. A component-based logic is a

A numerical study of the effect of uncertainties in ply angles and thicknesses on the flutter speed of a cantilevered composite plate wing was conducted in this paper. Reduction of the number of uncertain parameters was possible thanks to the use of

Multistable shells have been recently proposed as an effective solution to design morphing structures . We describe a class of shallow shells which are bistable after one of their sides, initially curved, is clamped along a flat line. Supposing the s

We have designed and tested experimentally a morphing structure consisting of a neutrally stable thin cylindrical shell driven by a multiparameter piezoelectric actuation. The shell is obtained by plastically deforming an initially flat copper disk,

International audience; Many examples of multi-stable shell structures have been recently proposed with the underlying hypothesis of the shell being completely free on its boundary. We describe a class of shallow shells which are bistable after one o

International audience; A shell can have multiple stable equilibria either if its initial curvature is suciently high or if a suitably strong pre-stress is applied. Under the hypotheses of a thin and shallow shell, we derive closed form results for t

The design of laminates with a minimum number of layers for obtaining the given elastic properties is addressed in the paper. The problem is treated and solved in the general case — no simplifying hypotheses are made about the type of their stackin
