This paper describes a new concept of an active honeycomb structure for morphing wingtip applications based on tubular inflatable systems and an auxetic cellular structure. A work-energy model to predict the output honeycomb displacement versus input pressure is developed together with a finite element formulation, and the results are compared with the data obtained from a small-scale example o...

Programmable materials are a novel development, in which specialized production processes used to introduce framework of information capabilities into the inner structure materials. Since design and fabrication programmable still challenging, this aims concept pave way toward industrial application. Herein, complex shape morphing has been implemented sense that changes response external conditi...

A tubular composite structure that is built of two materials, characterized by different Young moduli, is analysed in this paper. The Young's modulus of one of these materials can be controlled by external conditions e.g., magnetic or electric field, temperature etc. The geometry of the reinforcement is based on typical auxetic re-entrant honeycomb cellular structure. The influence of this exte...

We have presented some practical consequences on the moleculardynamics simulations arising from the numerical algorithm published recently in paper [1]. The algorithm is not a finite-difference method and therefore it could be complementary to the traditional numerical integrating of the motion equations. It consists of two steps. First, an analytic form of polynomials in some formal parameter ...
