Distribution of local elds in composites
نویسنده
چکیده
The behavior of composites depends crucially on the distribution of local elds. The ways to characterize and nd such distributions are poorly understood. In this paper, an attempt is made to present some simple approximate formulas for distributions of the local elds in variational problems. They are given in an explicit form for thermo-elastic composites and heat-conducting composites. The accuracy is tested for the case of heat conductivity of chess-board structures. Key words: Distribution of local elds, chess-board, composite, stress concentration

Electromagnetic Field Fluctuations and Optical Nonlinearities in Metal-dielectric Composites
A scaling theory of local "eld #uctuations and optical nonlinearities is developed for random metaldielectric composites near a percolation threshold. The theory predicts that in the optical and infrared spectral ranges the local "elds are very inhomogeneous and consist of sharp peaks representing localized surface plasmons (s.p.). The localization maps the Anderson localization problem describ...

In this research, the effect of different biopolymers such as polyethylene glycol (PEG) and polyvinylalcohol (PVA) on synthesis and characterization of polymer/cobalt ferrite (CF) nano-composites bymechanical alloying method has been systematically investigated. The structural, morphological andmagnetic properties changes during mechanical milling were investigated by X-ray diffraction (XRD),Fo...
متن کاملBounds the conductivity of some two-component composites
Calculation of third-order bounds to the conductivity of isotropic two-component composites is discussed. Coincidence of the Beran bounds and bounds derived using trial elds based on the solution of a single-body elec-trostatic boundary-value problem is demonstrated for a random distribution of impenetrable ellipsoids. This extends a proof of Beasley and Torquato J. A structural parameter relat...
متن کاملComputational evaluation of the homogeneity of composites processed by accumulative roll bonding (ARB)
A new computational method based on MATLAB was used to study the effect of different parameters on the homogeneity of composites produced by a severe plastic deformation technique known as accumulative roll bonding. For a higher number of passes, the degree of particle agglomeration and clustering decreased, and an appreciable homogeneity was obtained in both longitudinal and transverse directi...
متن کاملOptimization of SiC particle distribution during compocasting of A356-SiCp composites using D-optimal experiment design
This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...
