Molecular-dynamics simulations of the emergence of surface roughness in a polymer under compression
Vacher, Robin Sam; de Wijn, Astrid S. (Peer reviewed; Journal article, 2021)Roughness of surfaces is both surprisingly ubiquitous on all length scales and extremely relevant practically. The appearance of multi-scale roughness has been linked to avalanches and plastic deformation in metals. However, ... -
Nanoscale friction and wear of a polymer coated with graphene
Vacher, Robin Sam; de Wijn, Astrid S. (Journal article; Peer reviewed, 2022)Friction and wear of polymers at the nanoscale is a challenging problem due to the complex viscoelastic properties and structure. Using molecular dynamics simulations, we investigate how a graphene sheet on top of the ... -
Nanoscale Simulations of Wear and Viscoelasticity of a Semi-Crystalline Polymer
Vacher, Robin Sam; de Wijn, Astrid S. (Peer reviewed; Journal article, 2020)We investigate the underlying tribological mechanisms and running-in process of a semi-crystalline polymer using molecular-dynamics simulations. We subject a slab of simulated polyvinyl alcohol to a sliding contact asperity ... -
Nanoscale tribological simulations of a semi-crystalline polymer
Vacher, Robin Sam (Doctoral theses at NTNU;2022:95, Doctoral thesis, 2022)Many of the objects surrounding us are made of polymers. Those polymers are often used for their tribological properties, for example, shoes with rubber soles or car tyres. Polymers materials become more and more presents, ...
