High-density polyethylene (HDPE) is a widely used thermoplastic polymer with application as the material for pipeline transport systems. Due to the longterm, low-stress conditions of …
We discover a new, curvature-localizing, subcritical buckling mode that produces a shallow-kink configuration in multi-layer graphene. Our density functional theory (DFT) analysis reveals the mode …
Mechanical integrity of solid electrolyte interphase (SEI) plays an important role in determining the long-term reliability and performance of advanced high capacity anode materials. Failure …
Predicting crack patterns and toughness of structural biomaterials (SBs) is a complex problem due to their complicated microstructures. Most SBs are heterogeneous in nature and …
In this thesis, we studied the dynamic toughening mechanisms of a hierarchically nanostructured copolymer, polyurea. We first quantitively measured the dynamic fracture toughness as well …
Foams are widely used for impact protection. In order to utilize foams to their full potential a predictive model for their time-dependent mechanical deformation is …
Pressure-shear plate impact (PSPI) experiments have been performed on a polymer- bonded energetic material simulant and its constituents – a simulant crystal sucrose and an …
Stiff biological materials (SBMs), such as nacre and bone, are composites that display remarkable toughness enhancements over their primary constituents, which are brittle minerals. The …
Adhesion originated from van der Waals interactions becomes predominant over bulk properties of elastic solids at small length scales. A fundamental understanding of the mechanics …
Metallic alloys including high strength steels, refractory alloys, metallic glasses, and high entropy alloys have attracted great research interests in the past decade due to …
In 1959, physicist Richard Feynman gave a historical lecture: `There's Plenty of Room at the Bottom'. Even after sixty years, the exciting field of nanotechnology …
