Dr. Stone is a member of the American Society of Mechanical Engineers (ASME), the Society of Women Engineers (SWE), National Society of Black Engineers (NSBE), and Advancing Powder Metallurgy International (APMI).
SPECIALTY AREAS
Atomistic simulations of materials, microstructure-property constitutive modeling, modeling and simulation of powder metal consolidation.
RESEARCH SUMMARY
Dr. Stone’s research is focused on atomistic modeling and multiscale modeling of materials. She is particularly interested in capturing the structure-property relations during nanoparticle interations and deformation for inclusion in predictive models of powder metal (PM) consolidation. Dr. Stone is also studying the use of additives to reduce the porosity in aluminum castings.
RESEARCH INTERESTS
- Lightweighting of automotive PM components using material characterization experiments and predictive models to capture the material behavior throughout the manufacturing processes
- Modeling the consolidation of nanoparticles and nanostructured materials
- Using atomistic simulations to capture the material characteristics of nanopowder consolidation during mold filling in powder injection modeling (PIM) and micro-PIM processes
- Using molecular dynamics simulations to better understand the synthesis mechanisms related to grain size evolution during sintering
- Examining the use of electric fields to control grain growth in nanostructured materials during sintering
- Investigating the effect of gallium on oxide film formation in cast aluminum
