MECHANICS OF QUASI-BRITTLE MATERIALS
JAN ELIÁŠ
visiting professor in Department of Civil & Environmental Engineering, Northwestern University (from August to June 2020);
associate professor at Institute of Structural Mechanics, Faculty of Civil Engineering, Brno University of Technology, Czech Republic
Overview
Jan is visiting the Research Group from August to June 2020. He works as associate professor at Brno University of Technology in Czech Republic. His previous work was focused on modeling of fracture in concrete considering its random nature, development of discrete mesoscale models of concrete, improvements of mechanical solvers based on sequentially linear procedure and/or regularization techniques in continuous finite elements. His current projects involve research on coupled transport and mechanics and modeling of fatigue in concrete and simulations of mammary epithelial cell proliferation.
Current Research at Northwestern
Homogenization of coupled transport and mechanical phenomena
The asymptotic expansion homogenization is used to derive concurrent models of coupled phenomena of mechanics and transport in discrete models (LDPM). Macroscale model features standard continuous finite element formulation, the material routine involves solution of coupled problem within Representative Volume Element in periodic discrete setup.
