Abstract Stress and strain average rules are the key conceptual pillars of wide field continuum micromechanics materials. The aforementioned express that spatial (micro‐)stress (micro‐)strain fields throughout a microscopically finite representative volume element (RVE) equal to (macro‐)stress (macro‐)strain values associated with corresponding macroscopically infinitesimal (macroscopic materia...

In the analysis of textile-reinforced shell structures full-scale models are often impractical due to complex nature meso-structure. The structure is assumed be globally periodic which allows definition a representative volume element (RVE). this contribution, RVE embedded within first-order homogenisation framework, where meso-to-macro transition governed by Hill-Mandel condition. coupled mult...

Abstract Recently, several approaches for multiscale simulations problems with high contrast and no scale separation are introduced. Among them is nonlocal multicontinua (NLMC) method, which introduces multiple macroscopic variables in each computational grid. These explore the entire coarse block resolution one can obtain optimal convergence results independent of scales. However, these not am...

Abstract Paper has always been of great importance as a printing and packaging material. Due to its potential for recyclability reusability, which result in low environmental impact, it is expected that this will soar over the coming years. Nevertheless, even though paper use decades, many research questions are still open, especially field mechanics. One these appropriate size representative v...

Carbon nanotubes (CNTs) demonstrate unusually high stiffness, strength and resilience, and are therefore an ideal reinforcing material for nanocomposites. However, much work has to be done before the potentials of CNT-based composites can be fully realized.  Evaluating the effective material properties of such nanoscale materials is a very difficult tasks.  Simulations using molecular dynamics ...

The development of new type hydrogels featuring enhanced properties is a recent topic and particular interest for wide range industrial applications, especially in biomedical sector. present contribution focuses on the mutliscale modeling that are treated by enzymatic mineralization thus enriched with calcium phosphate. More specifically, phosphate forms spherical or honeycomb structures hydrog...

The need for quick and easy deflection calculations of various prefabricated slabs causes simplified procedures numerical tools to be used more often. Modelling full 3D finite element (FE) geometry such plates is not only uneconomical but often requires the use complex software advanced knowledge. Therefore, homogenization an excellent tool, which can easily employed simplify a model, especiall...

We analyze plane strain deformations of a representative volume element (RVE) to evaluate effective thermophysical parameters of a particulate composite comprised of two perfectly bonded heat conducting elasto-thermo-visco-plastic constituents. It is assumed that the composite is also isotropic and its response elasto-thermo-visco-plastic. Effective values of material parameters so computed are...

This study presents a hybrid method based on artificial neural network (ANN) and micro-mechanics for the failure prediction of IM7/8552 unidirectional (UD) composite lamina under triaxial loading. The ANN is trained offline by numerical data from high-fidelity micromechanics-based representative volume element (RVE) model using finite (FEM). RVE adopts identified constituent parameters inverse ...

Plant petioles and stems are hierarchical cellular structures, displaying geometrical features defined at multiple length scales. One or more of the intermediate hierarchical levels consists of tissues in which the cellular distribution is quasi-random, a factor that affects the elastic properties of the tissues. The current work focuses on the finite element analysis (FEA) of the constituent t...
