Based on Hill's lemma for classical Cauchy continuum, a version of Hill's lemma for micro-macro homogenization modeling of Cosserat continuum is derived. The derived admissible boundary conditions for the modeling are used to direct the proper prescription of boundary conditions on the representativ

A hybrid numerical model based on finite-element and discrete-element methods was verified for modelling the flow of granular materials in silos or bins. Laboratory experiments involving gravity flow of soybean from a parallel wall bin with length-to-width ratio of three (state of plane strain) were
A hybrid numerical model for the solution of bulk solids flow in silos and bins was used for the analysis of flow in symmetric and asymmetric rectangular bins. Seven analyses in symmetric bins with varying wall frictions, hopper slopes and discharge openings were carried out. In the four asymmetric
Accurate modeling and efficient analysis of the metal matrix composite materials failure mechanism during high velocity impact conditions is still the ultimate goal for many researchers. The objective is to develop a micromechanical constitutive model that can effectively simulate the high impact da
