Abstract

Most existing computational approaches are restrictive in their predictive capabilities by using non-representative virtual geometric domains (RVEs) of test materials. The strategy proposed here relaxes these restrictions by utilizing statistically representative 3D RVEs with appropriate boundary conditions and a robust homogenization implementation based on a micromechanical modelling philosophy. The strategy was implemented as a self-consistent, rigorous, virtual testing framework analogous to a physical experimental testing scheme. The strategy proposed in this work was shown to give a holistic set of elastic properties of the test composites considered when compared with other predictive approaches. Also, parametric studies were carried out to explore the different features of the virtual framework. Therefore, this virtual test-bed strategy represents a suitable substitute for realistic experiments and can be used in designing different virtual experiments.
