Projects

These projects address different physical systems, but they share a question: what physics and what resolution must a computational model retain to support reliable analysis and design? Ideas in multiscale modeling, interfaces, optimization and error control move from one problem to another.

Mechanics of granular media

Particle-resolved and multifidelity modeling of granular assemblies whose particles deform, break and rearrange under load.

Design of magnetic soft materials

Choosing where to put material and where to put magnetization, at the same time, so a soft structure moves the way a design problem asks it to.

Failure and fatigue in magnetic soft materials

Magnetic soft composites are designed as if the particle–matrix interface were perfect. This project asks what changes when it is not, and whether that is what sets how long the material keeps working.

Interface fracture in particle composites

Effective properties for a composite have to come from somewhere. This project derives them from resolved micro-scale fracture simulations, after first settling which description of the interface to trust.

Adhesion of field-responsive materials

A pull-off force is one number describing at least four different mechanisms. Separating them is what lets a measurement support a design rule that transfers, instead of one fitted curve.

Mathematical foundations of fracture

Well-posedness, kinetic relations and convergence rates for models of dynamic fracture, and the crack behavior they predict around voids, inclusions and interfaces.
