A new analytical model for the contact of Gaussian rough surfaces
Sihe Wang, Weike Yuan, Xuanming Liang +1
This paper advances an analytical incremental contact model for the purely elastic or elastic-perfectly plastic Gaussian rough surfaces. The contact is modelled by the accumulation…
A semi-analytical model for the scale-dependent friction of nanosized asperity
Jian Wang, Weike Yuan, Jianjun Bian +1
The friction of a nanosized sphere in commensurate contact with a flat substrate is investigated by performing molecular dynamics simulations. Particular focus is on the distributi…
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…
Anisotropic Deformation in the Compressions of Single Crystalline Copper Nanoparticles
Jianjun Bian, Hao Zhang, Xinrui Niu +1
Atomistic simulations are performed to probe the anisotropic deformation in the compressions of face-centred-cubic metallic nanoparticles. In the elastic regime, the compressive lo…
Spherical indentation on biological films with surface energy
Yue Ding, Wei-Ke Yuan, Gang-Feng Wang
Micro-/nano-indentations have been widely used to measure the mechanical properties of biological cells and tissues, but direct application of classical Hertzian contact model woul…
