Size-dependency and lattice-discreetness effect on fracture toughness in 2D crystals under antiplanar loading
Thuy Nguyen, Daniel Bonamy
Fracture toughness is the material property characterizing resistance to failure. Predicting its value from the solid structure at the atomistic scale remains elusive, even in the…
Effect of architecture disorder on the elastic response of two-dimensional lattice materials
Antoine Montiel, Thuy Nguyen, Cindy Rountree +3
We examine how disordering joint position influences the linear elastic behavior of lattice materials via numerical simulations in two-dimensional beam networks. Three distinct ini…
Role of particle aggregation on the structure of dried colloidal silica layers
Arnaud Lesaine, Daniel Bonamy, Cindy Rountree +3
The process of colloidal drying gives way to particle self-assembly in numerous elds including photonics or biotechnology. Yet, the mechanisms and conditions driving the nal partic…
How heat controls fracture: the thermodynamics of creeping and avalanching cracks
Tom Vincent-Dospital, Renaud Toussaint, Stéphane Santucci +6
While of paramount importance in material science, the dynamics of cracks still lacks a complete physical explanation. The transition from their slow creep behavior to a fast propa…
Highly porous layers of silica nano-spheres sintered by drying: Scaling up of the elastic properties from the beads to the macroscopic mechanical properties
Arnaud Lesaine, Daniel Bonamy, Georges Gauthier +2
Layers obtained by drying a colloidal dispersion of silica spheres are found to be a good benchmark to test the elastic behaviour of porous media, in the challenging case of high p…
Dynamics of cracks in disordered materials
Daniel Bonamy
Predicting when rupture occurs or cracks progress is a major challenge in numerous elds of industrial, societal and geophysical importance. It remains largely unsolved: Stress enha…
