Unifying temperature definition in atomistic and field representations of conservation laws
Youping Chen
This work presents a formalism to derive field quantities and conservation laws from the atomistic using the theory of distributions as the mathematical tool. By defining temperatu…
Recent Progress in the Concurrent Atomistic-Continuum (CAC) Method and its Application in Phonon Transport
Xiang Chen, Weixuan Li, Adrian Diaz +3
This work presents recent the progress in the development of the Concurrent Atomistic-Continuum (CAC) method for coarse-grained space- and time-resolved atomistic simulations of ph…
Ballistic-diffusive Phonon Heat Transport across Grain Boundaries
Xiang Chen, Weixuan Li, Liming Xiong +5
The propagation of a heat pulse in a single crystal and across grain boundaries (GBs) is simulated using a concurrent atomistic-continuum method furnished with a coherent phonon pu…
Passing Waves from Atomistic to Continuum
Xiang Chen, Adrian Diaz, Liming Xiong +2
Progress in the development of coupled atomistic-continuum methods for simulations of critical dynamic material behavior has been hampered by a spurious wave reflection problem at…
The origin of the distinction between microscopic formulas for stress and Cauchy stress
Youping Chen
Stress is calculated routinely in atomistic simulations. The widely used microscopic stress formulas derived from classical or quantum mechanics, however, are distinct from the con…
