……….where worlds collide: fluids & solids, soft & hard, tough & brittle, vivo and vitro!Keywords: Damage, fracture, rate dependence, toughness, topology, poroelasticity, quasi-continuum methods, network theory.
The long term objective of this research is to develop a rigorous understanding for the effect of micro-structure and local topology on deformation and failure of networked materials. Specific systems of interest include polymer networks as arising in hydrogels and soft tissues and trabecular networks in human bone. Current efforts focus on multi-scale constitutive modeling and fracture in soft materials including rate dependence, damage evolution, poro-mechanical effects and structure-function relations as well as the development of quasi-continuum models for domain decomposition in fractured lattice-like materials.
