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…
Highly Deformable Graphene Kirigami
Zenan Qi, Harold S. Park, David K. Campbell
Graphene's exceptional mechanical properties, including its highest-known stiffness (1 TPa) and strength (100 GPa) have been exploited for various structural applications. However,…
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…
A molecular simulation analysis of producing monatomic carbon chains by stretching ultranarrow graphene nanoribbons
Zenan Qi, Fengpeng Zhao, Xiaozhou Zhou +3
Atomistic simulations were utilized to develop fundamental insights regarding the elongation process starting from ultranarrow graphene nanoribbons (GNRs) and resulting in monatomi…
