Mechanism of Band Gap Formation in Beam Networks
Kwangmin Lee, Charles Emmett Maher, Katherine A. Newhall +1
Band gaps are commonly attributed to Bragg scattering or local resonance, yet it remains unclear whether these mechanisms govern band gap formation in beam networks. In this work,…

Dynamic Heterogeneity and Facilitation in Sheared Granular Materials: Insights from 3D Triaxial Testing
Kwangmin Lee, Brett S. Kuwik, Ryan C. Hurley
Strain localization in granular materials arises from complex microscale dynamics, including intermittent particle rearrangements and spatiotemporally correlated deformation. While…

The Interplay Between Forces, Particle Rearrangements, and Macroscopic Stress Fluctuations in Sheared 2D Granular Media
Kwangmin Lee, Ryan C. Hurley
Recent studies have established correlations between non-affine motion and macroscopic stress fluctuations in sheared granular media. However, a comprehensive examination of the re…
