Role of minimum adhesive wear particle size in third-body layer properties
Son Pham-Ba, Jean-François Molinari
We employ a novel discrete element method (DEM) force formulation to simulate adhesive wear and assess the effects of material and loading parameters on the properties of the third…
Adhesive wear with a coarse-grained discrete element model
Son Pham-Ba, Jean-François Molinari
The use of molecular dynamics (MD) simulations has led to promising results to unravel the atomistic origins of adhesive wear, and in particular for the onset of wear at nanoscale…
Experimental and numerical study of the effect of surface patterning on the frictional properties of polymer surfaces
Simone Balestra, Gianluca Costagliola, Amedeo Pegoraro +6
We describe benchmark experiments to evaluate the frictional properties of laser patterned low-density polyethylene as a function of sliding velocity, normal force and humidity. Th…
Velocity-driven frictional sliding: Coarsening and steady-state pulse trains
Thibault Roch, Efim A. Brener, Jean-Francois Molinari +1
Frictional sliding is an intrinsically complex phenomenon, emerging from the interplay between driving forces, elasto-frictional instabilities, interfacial nonlinearity and dissipa…
Adhesive wear regimes on rough surfaces and interaction of micro-contacts
Son Pham-Ba, Jean-François Molinari
We develop an analytical model of adhesive wear between two unlubricated rough surfaces, forming micro-contacts under normal load. The model is based on an energy balance and a cra…
An optimized material removal process
Jean-François Molinari, Son Pham-Ba
We conduct boundary element simulations of a contact problem consisting of an elastic medium subject to tangential load. Using a particle swarm optimization algorithm, we find the…
