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 ...
