Multiscale Modeling and Solid Mechanics

Multiscale Modeling and Solid Mechanics

This group specializes on multiscale modeling and experimentation spanning a broad spectrum of material properties and their behaviors at a range of spatial, temporal, and environmental conditions. Our focus includes mechanical behavior of advanced materials utilizing state-of-the-art experimental and computational approaches. In the realm of experimental mechanics, the mechanical behavior of aerospace composites, high strength structural ceramics, biomaterials, gels, and 3D printed materials is being investigated under multiaxial static and dynamic loads. These investigations encompass material length ranging from nanometers to several mm and loading time from nanoseconds (shock loading) to minutes.  The resulting experimental observations are validated using advanced computational approaches that span atomistic scales to macroscale behaviors. Research also encompasses atomistic and mesoscale simulation techniques to study the mechanical and thermodynamic properties of materials, with particular focus on the behavior of material interfaces.

In the realm of computational modeling, the research in the Atomistic and Multiscale Mechanics lab is focused on multiscale materials modeling and simulation.  Researchers develop formalisms to theoretically link atomistic and continuum descriptions. They also develop multiscale computational methods and massively parallel computing codes to predict nonequilibrium materials processes from the atomic to the mesoscale, with no empirical rules or parameters other than Newton’s second law and classical or machine-learned interatomic potentials. The ultimate goal of this research is to understand the physical processes and mechanisms underlying materials properties so as to design materials or structures to achieve co-optimized microstructural, mechanical, and thermal transport properties. Researchers are interested in high-strength high toughness materials, thermoelectric materials, phononics,  microelectronics, power electronics, and other semiconductor heterostructures.
