Numerical simulation of homogeneous turbulence
2008This paper describes the main results of direct simulation and large eddy simulation of homogeneous turbulence submitted to two kinds of constant mean velocity gradients. The Taylor microscale Reynolds number is in the range 20–70. The two strains considered are plane strain and solid body rotation.

Numerical Treatment of Homogeneous and Non-homogeneous Semi-Markov Reliability Models
Communications in Statistics - Theory and Methods, 2004In this paper, we extend to our knowledge, for the first case, some reliability results using homogeneous semi-Markov processes to the case of homogeneous modeling semi-Markov processes. Moreover, we apply some of our preceding results to give the numerical solutions and so the possibility to treat real life problems for which non-homogeneity in time ...

Numerical homogenization techniques applied to piezoelectric composites
The Journal of the Acoustical Society of America, 2003With the recent availability of piezoelectric fibers, the design and the analysis of piezoelectric composites needs new modeling tools. Therefore, a numerical homogenization technique has been developed, based on the ATILA finite element code, that combines two techniques: one relying upon the representative volume element (RVE) the other relying upon ...

Numerical Homogenization of Bone Microstructure
2010The presented study is motivated by the development of methods, algorithms, and software tools for μFE (micro finite element) simulation of human bones The voxel representation of the bone microstructure is obtained from a high resolution computer tomography (CT) image The considered numerical homogenization problem concerns isotropic linear elasticity

Recent developments in numerical homogenization [PDF]
, 2009 This paper deals with homogenization of non linear fibre-reinforced composites in the coupled thermomechanical field. For this kind of structures, i.e. inclusions randomly dispersed in a matrix, the self consistent methods are particularly suitable to describe the problem. Usually, in the framework of the self consistent scheme the homogenized material

Wavelets andWavelet Based Numerical Homogenization
2009Wavelets is a tool for describing functions on different scales or level of detail. In mathematical terms, wavelets are functions that form a basis for with special properties; the basis functions are spatially localized and correspond to different scale levels.

Wavelet-Based Numerical Homogenization with Applications
2002Classical homogenization is an analytic technique for approximating multiscale differential equations. The numbers of scales are reduced and the resulting equations are easier to analyze or numerically approximate. The class of problems that classical homogenization applies to is quite restricted.

Stochastic homogenization: Theory and numerics
2015In this chapter, we pursue two related goals. First, we derive a theoretical stochastic homogenization result for the stochastic forward problem introduced in the first chapter. The key ingredient to obtain this result is the use of the Feynman-Kac formula for the complete electrode model.
