A finite geometry, inertia assisted coarsening-to-complexity transition in homogeneous frictional systems
Thibault Roch, Efim A. Brener, Jean-François Molinari +1
The emergence of statistical complexity in frictional systems, manifested in broad distributions of various observables, is not yet understood. We study this problem in velocity-dr…
Mesh d-refinement: a data-based computational framework to account for complex material response
Sacha Wattel, Jean-François Molinari, Michael Ortiz +1
Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutiv…
Dynamic crack front deformations in cohesive materials
Thibault Roch, Mathias Lebihain, Jean-François Molinari
Crack fronts deform due to heterogeneities, and inspecting these deformations can reveal local variations of material properties, and help predict out of plane damage. Current mode…
Quasi-static crack front deformations in cohesive materials
Mathias Lebihain, Thibault Roch, Jean-François Molinari
When a crack interacts with material heterogeneities, its front distorts and adopts complex tortuous configurations that are reminiscent of the energy barriers encountered during c…
Predicting damage in aggregates due to the volume increase of the alkali-silica reaction products
Emil R. Gallyamov, Andreas Leemann, Barbara Lothenbach +1
Volume increase between the reactants and the products of alkali silica reaction could reach up to 100%. Taking place inside the aggregates, ASR imposes internal pressure on the su…
Effect of wear particles and roughness on nanoscale friction
Tobias Brink, Enrico Milanese, Jean-François Molinari
Frictional contacts lead to the formation of a surface layer called the third body, consisting of wear particles and structures resulting from their agglomerates. Its behavior and…
