Why soft contacts are stickier when breaking than when making them

Antoine Sanner, Nityanshu Kumar, Ali Dhinojwala +2

Insects, pick-and-place manufacturing, engineered adhesives, and soft robots employ soft materials to stick to surfaces even in the presence of roughness. Experiments show that the…

contact.engineering -- Create, analyze and publish digital surface twins from topography measurements across many scales

Michael C. Röttger, Antoine Sanner, Luke A. Thimons +6

The optimization of surface finish to improve performance occurs largely through trial and error, despite significant advancements in the relevant science. There are three central…

Crack-front model for adhesion of soft elastic spheres with chemical heterogeneity

Antoine Sanner, Lars Pastewka

Adhesion hysteresis can be caused by elastic instabilities that are triggered by surface roughness or chemical heterogeneity. However, the role of these instabilities in adhesion h…

Hard-material Adhesion: Which Scales of Roughness Matter?

Luke A. Thimons, Abhijeet Gujrati, Antoine Sanner +2

Surface topography strongly modifies adhesion of hard-material contacts, yet roughness of real surfaces typically exists over many length scales. This investigation aims to determi…

Scale-dependent roughness parameters for topography analysis

Antoine Sanner, Wolfram G. Nöhring, Luke A. Thimons +2

The failure of roughness parameters to predict surface properties stems from their inherent scale-dependence; in other words, the measured value depends on the way it was measured.…

Comprehensive topography characterization of polycrystalline diamond coatings

Abhijeet Gujrati, Antoine Sanner, Subarna R. Khanal +4

The surface topography of diamond coatings strongly affects surface properties such as adhesion, friction, wear, and biocompatibility. However, the understanding of multi-scale top…
