Please join us for a talk entitled:

Investigating the plastic deformation of disordered nanoparticle packings

with Dr. Joel Lefever

The mechanics of disordered materials, including glasses and granular materials, remain an open research question despite substantial research progress. One class of materials, disordered nanoparticle packings, is a convenient material system to investigate because they can be imaged and probed at a single constituent level using an atomic force microscope (AFM). Mechanical properties measured using AFM-based nanoindentation show that nanoparticle packings share many similarities with other disordered materials. In addition, their strength and ductility can be varied by adjusting environmental conditions, such as humidity. The information learned here has implications for how these materials might be toughened, thus improving their potential for commercial applications.
