Nanotube heat conductors under tensile strain: Reducing the three-phonon scattering strength of acoustic phonons
Daniel Bruns, Alireza Nojeh, A. Srikantha Phani +1
Acoustic phonons play a special role in lattice heat transport, and confining these low-energy modes in low-dimensional materials may enable nontrivial transport phenomena. By appl…
Residual stress distributions in athermally deformed amorphous solids from atomistic simulations
Céline Ruscher, Jörg Rottler
The distribution of local residual stresses (threshold to instability) that controls the statistical properties of plastic flow in athermal amorphous solids is examined with an ato…
An Atomistic Study of Diffusion-Mediated Plasticity and Creep using Phase Field Crystal Methods
Joel Berry, Jörg Rottler, Chad W. Sinclair +1
The nonequilibrium dynamics of diffusion-mediated plasticity and creep in materials subjected to constant load at high homologous temperatures is studied atomistically using Phase…
Phase Field Crystal Modeling as a Unified Atomistic Approach to Defect Dynamics
Joel Berry, Nikolas Provatas, Jörg Rottler +1
Material properties controlled by evolving defect structures, such as mechanical response, often involve processes spanning many length and time scales which cannot be modeled usin…
Time dependent elastic response to a local shear transformation in amorphous solids
Francesco Puosi, Joerg Rottler, Jean-Louis Barrat
The elastic response of a two-dimensional amorphous solid to induced local shear transformations, which mimic the elementary plastic events occurring in deformed glasses, is invest…
Defect stability in phase-field crystal models: Stacking faults and partial dislocations
Joel Berry, Nikolas Provatas, Jörg Rottler +1
The primary factors controlling defect stability in phase-field crystal (PFC) models are examined, with illustrative examples involving several existing variations of the model. Gu…
