This study presents a new numerical approach using tools developed to perform molecular simulation investigate the wall effect on aggregates and mortar distribution in concrete. Aggregates are represented by spheres interacting via generalized truncated Lennard-Jones potential. allows obtaining particle profiles according reference frame of interest (e.g., confined directions). Then particle-ba...

In this work, elastic fiber reinforced composite materials consisting of several layers are considered. Each layer is assumed to be a unidirectional composite. The interface between perfect, which means the displacement and traction through interfaces continuous. To predict overall behavior considered two step homogenization procedure first step, effective properties predicted based on Mori-Tan...

We consider two problems related to polar codes. First is the problem of polar codes construction and analysis of their performance without Monte-Carlo method. The formulas proposed are the same as those in [Mori-Tanaka], yet we believe that our approach is original and has clear advantages. The resulting computational procedure is presented in a fast algorithm form which can be easily implemen...

In this study, the dynamic buckling of the embedded laminated nanocomposite plates is investigated. The plates are reinforced with the single-walled carbon nanotubes (SWCNTs), and the Mori-Tanaka model is applied to obtain the equivalent material properties of them. Based on the sinusoidal shear deformation theory (SSDT), the motion equations are derived using the energy method and Hamilton's p...

Many brittle materials, such as concrete, piezoelectricity, have a large number of preexisting microcracks, The determination of their effective material properties has been the focus of considerable research. Current research into the development of effective material properties has mostly concentrated on the Taylor's method[l], the self-consistent method[2], the differential theory[3], the Mo...

We propose in this paper a novel hybrid numerical modeling method for computing electromagnetic scattering from inhomogeneous targets containing honeycomb structures. In the proposed approach, whole structure is divided into inner and outer two subregions. Each thin wall of unit cell subregion replaced by zero-thickness surface, with aid resistive sheet boundary condition (RSBC) to describe ele...

A continuum-based elastic micromechanics model is developed for silica nanoparticle/polyimide composites with various nanoparticle/polyimide interfacial treatments. The model incorporates the molecular structures of the nanoparticle, polyimide, and interfacial regions, which are determined using a molecular modeling method that involves coarse-grained and reversemapping techniques. The micromec...

In this paper, a multiscale method is developed to predict Young's modulus of fullerene-reinforced polymer nanocomposites (FRPNs). Polymethyl methacrylate chosen as the matrix, while C60 fullerene considered reinforcement. First, molecular dynamics (MD) simulations are conducted calculate Young nanocomposite unit cell with different weight fractions fullerene. Then, micromechanics model for com...
