Welcome to Dynamic Property Research Lab
Introduction
Research in the Dynamic Properties Research Laboratory at Georgia Tech concerns material behavior over a wide range of length scales. Issues of interest include
- novel mechanical behaviors of metal nanowires such as shape memory and pseudoelasticity with recoverable strains up to 50%
- thermomechanical behavior of nanocomponents made of semiconducting materials such as ZnO and GaN
- phase transformations in nanomaterials and their effects on thermomechanical coupling and thermoelectric coupling
- strength and deformation of nanostructured polycrystalline materials such as Al and Fe2O3 and their composites
- equivalent continuum (EC) representations of atomistic systemseffects of microstructures of heterogeneous materials on fracture toughness
- fracture in ceramics and metals
Research approaches employed emphasize both high-performance computational finite element and molecular dynamics simulations and experimental characterizations using laser interferometry and novel digital diagnostics. A variety of quasistatic and dynamic deformation and loading conditions encountered in engineering applications are considered. The computational and experiments techniques allow for explicit account of material mesoscopic, microscopic, and nanoscopic structures. The objectives are to outline factors, mechanisms and conditions that enhance material performance under given conditions, to provide guidance for the enhancement of performance, and to facilitate the design of materials with specified functionalities.
