Magnetic hybrid-materials multi-scale modelling, synthesis, and applications by Stefan Odenbach( )

1 edition published in 2021 in English and held by 137 WorldCat member libraries worldwide

Externally tunable properties allow for new applications of magnetic hybrid materials containing magnetic micro- and nanoparticles in sensors and actuators in technical and medical applications. By means of easy to generate and control magnetic fields, changes of the internal particle arrangements and the macroscopic properties can be achieved. This monograph delivers the latest insights into multi-scale modelling, experimental characterization, manufacturing and application of those magnetic hybrid materials

Modeling and simulation of hydrogels for the application as finger grippers( )

in English and held by 1 WorldCat member library worldwide

A chemo-electro-mechanical continuum model developed previously by the authors is utilized in this article to simulate electrically driven hydrogels for the application as finger grippers. To that end, a system consisting of an anionic gel and a cationic gel immersed in NaCl solution bath is discretized and numerically solved. An electric field is then applied between two electrodes on top and bottom of the simulation domain. For the numerical treatment of this study, the finite element method is exploited. By gradual increase in the electric potential between the two electrodes, the bending movement of the gels is realized. The process leading to bending of the gels is elaborated in detail in this article. It is concluded that our approach proves to be a practical tool for simulation of the closing and opening mechanism of a finger gripper stimulated by electric field
Structural optimization of an aeroelastically tailored composite wing by Abdolhamid Attaran( Book )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

Effects of the aspect ratio, sweep angle, and stacking sequence of laminated composites were studied to find the optimized configuration of an aeroelasticity tailored composite wing idealized as a flat plate in terms of flutter speed. The aeroelastic analysis has been carried out in frequency-domain. The modal approach in conjunction with Doublet-lattice Method (DLM) has been opted for structural and unsteady aerodynamic boxes amd structural nodes has been using surface spline. To study the effect of stacking sequence the classical lamination theory (CLT) has been chosen. The parametric studies showed the effective ply orientation angle to be somewhere between 15 to 30 degree, while the plates with lower aspect ratio seems to have higher flutter speed. Forward-swept configurations show higher flutter speed, yer imposed by divergence constraint
