The sensitivity of the shear moduli is determined against the various cell geometry parameters. Good agreement between the analytical and numerical simulations is observed. We show that the specific curved wall honeycomb configuration applicated in plates witch build the structure of the wind turbines proposed in this paper possesses a high flexibly compared to the classical hexagonal cell, This leads to the needs of the wind turbine industry to minimize the weight of the wings and also to have a significant flexibility against the wind and the other external dynamic solicitations.

The volume contains twenty four papers. Twenty one of them, on auxetic materials and models, are grouped in three sections: three-dimensional (3D) auxetics, quasi-two-dimensional (Q2D) auxetics, and two-dimensional (2D) auxetics. The remaining papers concern other systems with “negative” characteristics.
