Welcome

Welcome to Dr. Tonya Stone’s Particulate Materials Research Group at Mississippi State University.  Our group is interested in quantifying the structure-property relationships of particulate materials across multiple length scales, with specific interest on the mechanical behavior of nanostructured materials.  Our goals are to quantify processing parameters and ensuing mechanical and thermal properties, quantify the consolidation behavior based on densification and microstructure responses, develop a constitutive model that accurately describes the responses of particulate materials, and develop a simple, accurate predictive model for the performance of nanostructured microdevices.

Currently, the fabrication of nanostructured devices using nanopowders is limited.  Additionally, the cost of experimentally evaluating the feasibility of these devices and moves toward implementation are expensive and time consuming.

Our research is primarily focused on studying consolidation techniques using a multiscale computational approach.  We are particularly interested in capturing the structure-property relations during particle interactions and deformation for inclusion in predictive models of powder metal consolidation at multiple length scales.
