The Physics of Topological Defects in Glasses
Arabinda Bera, Peter Schall, Timothy W. Sirk +2
Topological defects play a central role in the mechanical behavior of crystalline materials, yet their relevance to amorphous solids has only recently begun to emerge. Over the las…
Geometric indicators of local plasticity in glasses measured by scanning small-beam diffraction
Amelia C. Y. Liu, Huyen Pham, Arabinda Bera +7
The notion of defects in crystalline phases of matter has been extremely powerful for understanding crystal growth, deformation and melting. Many of these discontinuities in the pe…
Universal inverse-cube thickness scaling of projectile penetration energy in ultrathin films
Alessio Zaccone, Tim W. Sirk
Ultrathin films of widely different materials exhibit a dramatic enhancement of projectile penetration resistance under high--velocity impact. Despite extensive simulations and exp…
Atomistic Framework for Glassy Polymer Viscoelasticity Across Twenty Frequency Decades
Ankit Singh, Vinay Vaibhav, Caterina Czibula +6
Glassy polymers are central to engineering applications, yet their viscoelastic response over broad frequency and temperature ranges remains difficult to characterize. We extend no…
Microscopic origin of shear bands in 2D amorphous solids from topological defects
Arabinda Bera, Debjyoti Majumdar, Timothy W. Sirk +2
The formation of shear bands in amorphous solids such as glasses has remained an open question in our understanding of condensed matter and amorphous materials. Unlike in crystals,…
Viscosity of polymer melts using non-affine theory based on vibrational modes
Ankit Singh, Vinay Vaibhav, Alessio Zaccone
Viscosity, a fundamental transport and rheological property of liquids, quantifies the resistance to relative motion between molecular layers and plays a critical role in understan…
