CEAD develops computational methods for materials that fracture, crush, stick and reorganize. The group studies which physical mechanisms a model must retain, and how approximation error affects the decision made from a simulation.

How electric and magnetic fields interact with microstructure, interfaces and geometry, and how those interactions determine actuation, adhesion and degradation in soft composites.
5 papers 3 researchers Two lineages: coarse graining of field–material coupling since 2016, soft-composite design and adhesion since 2025
The full argumentHow matrix cracking, interface debonding, particle fracture and contact interactions compete to control strength, toughness, localization and residual load capacity.
19 papers 1 researcher
The full argumentHow residuals, error estimates and targeted high-fidelity solves can determine when a reduced or learned model is accurate enough for inference, optimization or design.
11 papers
The full argumentMachine design five semesters running, solid mechanics, applied finite element analysis, and a graduate finite element course — six courses across three institutions since 2021. Three graduate students and an undergraduate alumna, an open textbook written as the graduate course runs, and twelve notebooks anyone can execute.

We are recruiting graduate and undergraduate researchers interested in computational mechanics, fracture, and scientific machine learning. Prior HPC or FEM experience helps but is not required.
