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…
Stick-slip phenomena and Schallamach waves captured using reversible cohesive elements
Evelyne Ringoot, Thibault Roch, Jean-François Molinari +2
Reversibility is of paramount importance in the correct representation of surface peeling in various physical settings, ranging from motility in nature, to gripping devices in robo…
Creation and evolution of roughness on silica under unlubricated wear
Son Pham-Ba, Jean-François Molinari
Friction and wear are important phenomena occurring in all devices with moving parts. While their origin and the way they evolve over time are not fully understood, they are both i…
Variational phase-field continuum model uncovers adhesive wear mechanisms in asperity junctions
Sylvain Collet, Jean-François Molinari, Stella Brach
Wear is well known for causing material loss in a sliding interface. Available macroscopic approaches are bound to empirical fitting parameters, which range several orders of magni…
Multi-scale modelling of concrete structures affected by alkali-silica reaction: Coupling the mesoscopic damage evolution and the macroscopic concrete deterioration
Emil R. Gallyamov, Aurelia Isabel Cuba Ramos, Mauro Corrado +2
A finite-element approach based on the first-order FE 2 homogenisation technique is formulated to analyse the alkali-silica reaction-induced damage in concrete structures, by linki…
A parameter-free mechanistic model of the adhesive wear process of rough surfaces in sliding contact
Tobias Brink, Lucas Frérot, Jean-François Molinari
In order to develop predictive wear laws, relevant material parameters and their influence on the wear rate need to be identified. Despite decades of research, there is no agreemen…
