Multiple scale analysis of heterogeneous elastic structures using homogenization theory and voronoi cell finite element method
TL;DR: In this article, the authors deal with the development of a multiple scale finite element method by combining the asymptotic homogenization theory with Voronoi cell (VCFEM) for microstructural modeling.

Elastic-plastic analysis of arbitrary heterogeneous materials with the Voronoi Cell finite element method
Somnath Ghosh,Suresh Moorthy +1 more
TL;DR: In this article, a Voronoi cell finite element method is developed to solve small deformation elastic-plasticity problems for arbitrary heterogenous materials, which is based on Dirichlet Tessellation of microstructural representative materials.

Experimental and numerical studies of the effect of particle size on the deformation behavior of the metal matrix composites
Yi Wu Yan,Lin Geng,A.B. Li +2 more
TL;DR: In this article, the effect of particle size on the deformation behavior of the metal matrix composites was investigated by incorporating the Taylor-based nonlocal theory of plasticity, and the finite element method (FEM) was applied to investigate the effect.

Deformation of metal-matrix composites with continuous fibers: geometrical effects of fiber distribution and shape
TL;DR: In this article, the effects of fiber distribution and of fiber cross-sectional geometry on the deformation of a metal-matrix composite reinforced with continuous fibers were analyzed. And the influence of such constraint on the geometry dependence of deformation was examined.

Properties of n -dimensional triangulations
TL;DR: A number of mathematical results relevant to the problem of constructing a triangulation, i.e., a simplical tessellation of the convex hull of an arbitrary finite set of points in n-space are established.
