When are rough surfaces sticky?
Lars Pastewka, Mark O. Robbins
At the molecular scale there are strong attractive interactions between surfaces, yet few macroscopic surfaces are sticky. Extensive simulations of contact by adhesive surfaces wit…
Defining Contact at the Atomic Scale
Shengfeng Cheng, Mark O. Robbins
Molecular dynamics simulations are used to study different definitions of contact at the atomic scale. The roles of temperature, adhesive interactions and atomic structure are stud…
Contact and Friction of Nano-Asperities: Effects of Adsorbed Monolayers
Shengfeng Cheng, Binquan Luan, Mark O. Robbins
Molecular dynamics simulations are used to study contact between a rigid, nonadhesive, spherical tip with radius of order 30nm and a flat elastic substrate covered with a fluid mon…
Strain Hardening in Polymer Glasses: Limitations of Network Models
Robert S. Hoy, Mark O. Robbins
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While traditional entropic network models can be fit to the total stress, their unde…
Contact of Single Asperities with Varying Adhesion: Comparing Continuum Mechanics to Atomistic Simulations
Binquan Luan, Mark O. Robbins
Atomistic simulations are used to test the equations of continuum contact mechanics in nanometer scale contacts. Nominally spherical tips, made by bending crystals or cutting cryst…
Resolving singular forces in cavity flow: Multiscale modeling from atoms to millimeters
Xiaobo Nie, Mark. O. Robbins, Shiyi Chen
A multiscale approach for fluid flow is developed that retains an atomistic description in key regions. The method is applied to a classic problem where all scales contribute: The…
