One of the most famous methods to predict the stiffness of short fiber composites is micromechanical modeling. In this study, a Representative Volume Element (RVE) of a beech wood flour natural composite has been designed and the orientation averaging approach has been utilized to predict its stiffness tensor. The novelty of this work is in finding the proper fiber orientation distribution func...

This short communication discusses an algorithm suited for the generation of periodic microstructures of granular media. Its particular features are a user-defined grain size distribution, a representative volume element which is intrinsically periodic ab initio and a user-defined termination criterion, controlled by an increase of volume fraction. For low densities our particle packings resemb...

In response to the global trend of carbon reduction over last few years, various industries, including aviation and automobile have gradually begun research, design, production fiber composite materials. These excellent mechanical properties, such as being lightweight, high strength, rigidity, which provide weight energy savings in applications across many fields. When used a load-beam structur...

• Effects of particle shape and sample density on representative element volume (REV) for granular materials were investigated. The minimum REV reduces with increasing packing density. is sensitive to the characteristics measured. Analysis fluctuations around critical state stress ratio can be used determine REV. number contacts in samples indicates effect aspect Numerical studies particles or ...

The accurate prediction of the thermomechanical properties newly developed polymer composites is important in determination their possible areas application. In this study, a 3D model representative volume element (RVE) with different wood flour weight ratios (5, 10, 15, 20, 25 and 30 %) was used to develop composites. Micromechanical material modelling software (Digimat) conjunction finite ana...

Abstract We study the representative volume element (RVE) method, which is a method to approximately infer effective behavior $$a_{\textrm{hom}}$$ a hom of stationary random medium. The latter described by coefficient field ( x ) generated from given ensemble $$\l...
