Study of methods for simulating multiphase construction materials

Abstract

Computer-aided design and multiscale modeling and analysis can lead not only to a better understanding of the behavior of multiphase materials or increased performance, but also reduced energy consumption and raw materials, optimization and cost reduction. Generally, concept modeling involves multiscale analysis, which occurs at two or more levels, from the smallest scale (micro- or even nano-structure) to full system level (macroscopic scale). The purpose of this paper is to analyze the simulation feasibility of multiphase materials (traditional mortar), and also the comparison methods that can be applied in this regard.This paper introduces a multiscale modeling approach to simulate the effective (macroscopic) mechanical properties of the ordinary cement-based mortar. Simulations of multiphase materials have been done by mean-field homogenization techniques and the finite element method. Multiscale modeling helps to evaluate the stress–strain behavior and reveals important engineering properties, such as Young’s Modulus and Poisson’s ratio.
