RESEARCH PROJECT

  • Concurrent material and structure optimization of multiphase hierarchical systems
    In this project, we develop a concurrent material and structure optimization framework for hierarchical systems that relies on continuum micromechanics estimates for multiscale analysis. The analytical nature of these estimates enables simple constraint optimization problems at the material level that are essentially independent of the number of hierarchical scales, rendering our framework computationally tractable for multiphase hierarchical systems. After successfully establishing the framework for overall linear elastic behavior, we are currently working on extending our framework to inelasticity that originates from the material microscales in hierarchical systems. The methodology developed in this project could open up new possibilities for genetic tailoring of plant materials, multiscale bone remodeling, or fabrication of bioinspired engineering materials.

  • Research focus

    My research interests are in computational mechanics, finite element analysis and multiscale material modeling. I primarily focus on the development of image-through-analysis tools for the simulation of multiphysics and multiscale mechanical systems. The main application driving my work is strength and stability assessment of cereal crops with the goal of possibly breeding lodging resistant crops.
