In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...

A study is presented of the axially symmetric deformation of a non-homogeneous elastic halfspace subjected to torsional shear tractions that are linearly distributed over a circular portion of the otherwise free surface. The problem is formulated in terms of Hankel integral transforms and an inverse procedure is implemented in which the determination of the type of non-homogeneity constitutes p...

A simple model of cleavage in brittle crystals consists of a layer of material containing N atomic planes separating in accordance with an interplanar potential under the action of an opening displacement δ prescribed on the boundary of the layer. The problem addressed in this work concerns the characterization of the constrained minima of the energy EN of the layer as a function of δ as N beco...

Abstract In this study the isogeometric B-Rep mortar-based mapping method for geometry models stemming directly from Computer-Aided Design (CAD) is systematically augmented and applied to partitioned Fluid-Structure Interaction (FSI) simulations. Thus, newly proposed methodology geometries described by their Boundary Representation (B-Rep) in terms of trimmed multipatch Non-Uniform Rational B-S...

In this article, small scale effects on free vibration analysis of non-uniform nanobeams is discussed. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width among the beams length with constant thickness. Analytical solution is achieved for free vibration with different boundary conditions. It is shown th...
