Materials modeling and simulation
In recent decades, various kinds of novel composite materials have been researched in the construction field. As these new materials are developed, the prediction of the enhanced characteristics and functionality should be investigated.
Using the micromechanics-based modeling and the ensemble volume averaged method, the electrical, thermal, and mechanical properties of the composite materials can be predicted. Especially, the characteristics of the composite materials incorporating various types of conductive fillers have been modeled using micromechanics.
In addition, multiscale modeling combining molecular dynamics, micromechanics and finite element method allows the investigation of composite materials at each length scale, which is necessary for the modeling of materials with significant heterogeneities at different length scales. The behavior of ultra-high performance concrete (UHPC), which has a complex microstructure, has been investigated through the multiscale modeling scheme.
