Computing the intrinsic grain boundary mobility tensor
Xinyuan Song, Liang Yang, Chuang Deng
Grain boundary (GB) mobility has been conventionally computed as a single value; however, a recent study has suggested that GB mobility should be expressed as a tensor. In this wor…

Statistical characterization of the yield stress of nanoparticles
Liang Yang, Jianjun Bian, Weike Yuan +1
Atomistic simulations are performed to study the statistical mechanical property of gold nanoparticles. It is demonstrated that the yielding behavior of gold nanoparticles is gover…
