چکیده
We discuss the use of homogenization techniques to derive approximate models with simple geometry for physical models of grids and trusses which have a complex geometry that gives rise to computational diiculties. Our presentation is in the context of inverse or parameter estimation problems for composite material structures with unknown characteristics such as stiiness and internal damping. We present the necessary theoretical foundations for this approach and discuss comparison of modal properties of the resulting homogenization model for a two-dimensional grid structure with modal properties observed in experiments with this grid.

Today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. One of the almost endless and pure energy which have been paid attention over the years is the solar energy. Solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. Significant improvement has been made...
متن کاملParameter Estimation Versus Homogenization Techniques in Time-Domain Characterization of Composite Dielectrics
We compare an inverse problem approach to parameter estimation with homogenization techniques for characterizing the electrical response of composite dielectric materials in the time domain. We first consider an homogenization method, based on the periodic unfolding method, to identify the dielectric response of a complex material with heterogeneous micro-structures which are described by spati...

متن کاملHomogenization of strongly heterogeneous porous media
Resumé Homogenization techniques were developed to simplify description and modeling of heterogeneous structures where the characteristic size of the heterogeneities is much smaller than the size of the whole structure. Usually the simplification is associated with tractabil-ity of numerical modeling: " original structures " , like fiber composites, or masonry are constructed by repeating some ...
متن کاملAnalytical estimation of natural frequency in earth dams with respecting to the foundation effects
There are varieties of techniques for calculating natural frequency of the structures. Nevertheless, these equations are less developed in the geotechnical structures such as slopes, buttress group, dams, and retaining walls. In earth dams, with respecting to the dimensions and weight of dam, soil-structure interaction is of prime importance for finding seismic parameters including natural freq...
