David Henann received a Ph.D. in Mechanical Engineering from MIT in 2011, followed by postdoctoral appointments at MIT and Harvard. He became an Assistant Professor of Engineering at Brown University in the Fall of 2013. His research interests are in the area of theoretical and computational solid mechanics.
My research focuses on the formulation of new continuum-level constitutive theories for describing material behavior and the quantitative modeling of material behavior through numerical simulation. I am particularly interested in materials that exhibit coupled and size-dependent phenomena.
Some areas of ongoing research include:
1. Constitutive models for granular materials.
2. Simulation techniques for nonlocal models for granular media.
3. Modeling of multi-physics phenomena in soft elastic materials, in particular, dielectric elastomers.
