Surface Shear Transformation Zones in Amorphous Solids
Penghui Cao, Xi Lin, Harold S. Park
We perform a systematic study of the characteristics of shear transformation zones (STZs) that nucleate at free surfaces of two-dimensional amorphous solids subject to tensile load…

Strain-rate and temperature dependence of yield stress of amorphous solids via self-learning metabasin escape algorithm
Penghui Cao, Xi Lin, Harold S. Park
A general self-learning metabasin escape (SLME) algorithm~\citep{caoPRE2012} is coupled in this work with continuous shear deformations to probe the yield stress as a function of s…

Strain-rate and temperature-driven transition in the shear transformation zone for two-dimensional amorphous solids
Penghui Cao, Harold S. Park, Xi Lin
We couple the recently developed self-learning metabasin escape algorithm, which enables efficient exploration of the potential energy surface (PES), with shear deformation to eluc…
