Journal ArticleDOI
Analysis of indentation loading curves obtained using conical indenters
Yang-Tse Cheng,Che-Min Cheng +1 more
TL;DR: In this article, the functional form of indentation loading curves for a rigid conical indenter indenting into elastic-perfectly plastic solids was determined using dimensional analysis and finite-element calculations.
Journal ArticleDOI
Effects of stress on lithium transport in amorphous silicon electrodes for lithium-ion batteries
Jie Pan,Qinglin Zhang,Qinglin Zhang,Juchuan Li,Matthew J. Beck,Xingcheng Xiao,Yang-Tse Cheng +6 more
TL;DR: In this article, the authors established a relationship between stress and the diffusion coefficients of Li in amorphous Si by ab initio molecular dynamics calculations (AIMD), and the prediction from AIMD was validated by the potentiostatic intermittent titration measurements.
Journal ArticleDOI
Unravelling the Impact of Reaction Paths on Mechanical Degradation of Intercalation Cathodes for Lithium-Ion Batteries.
Juchuan Li,Qinglin Zhang,Qinglin Zhang,Xingcheng Xiao,Yang-Tse Cheng,Chengdu Liang,Nancy J. Dudney +6 more
TL;DR: This work envisions a strategy for rationally designing stable cathodes for lithium-ion batteries through engineering the atomic structure that extends the solid-solution region and suppresses phase transformation attributed to the superior electrochemical performance of disordered spinel.
Journal ArticleDOI
A nanoindentation study of the viscoplastic behavior of pure lithium
Yikai Wang,Yang-Tse Cheng +1 more
TL;DR: In this paper, a viscoplastic constitutive law for Li was determined based on an iterative finite element (FE) modeling approach, and it was shown that elastic modulus has a negligible influence on the nanoindentation response of Li at ambient temperature.
Journal ArticleDOI
Friction anisotropy at Ni(100)/(100) interfaces: Molecular dynamics studies
TL;DR: In this article, a series of nonequilibrium molecular dynamics simulations at 300 K for sliding of Ni(001)/Ni(001) interfaces under a constant shear force was carried out, showing that small amounts of roughness dramatically increase the friction on incommensurate surfaces.
