Multifunctional 3D Printable Polymer-Metal Composites

Ongoing
Recent advances in additive manufacturing (AM) have positioned metals and polymers as two key materials. Typically, AM of these two materials involves incompatible methods and conditions. The novel multifunctional polymer-metal composites in this project incorporate low-melting alloys with

Advanced Mechanical Characterization of Mesoscale Materials

Ongoing
Knowledge of a material’s mechanical properties is key to designing safe and reliable structural components for applications ranging in size from medical implants to large civil engineering structures. Traditionally, a material’s mechanical properties are measured by performing mechanical tests on
complex oxides

Measurements of Point-Defect Chemistry in Complex Oxides

Ongoing
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide
High Impact Ballistic Testing of Polymer Films

Polymer Mechanics

Ongoing
The mechanical behavior for polymers is very sensitive to the deformation rate of the impact test. Thus we are developing and applying several novel measurements that can study the mechanical response of the polymer at different deformation rates and at different material length scales. High-rate
