Mesoscopic formulas of linear and angular momentum fluxes
Antoine Fruleux, Ken Sekimoto
Many approaches of coarse-graining have been developed under the names of Cosserat theory or polar-fluid theory, for those materials in which some component elements undergo non-af…
Internal stress as a link between macroscale and mesoscale mechanics
Ken Sekimoto
The internal (or residual) stress is among the key notions to describe the state of the systems far from equilibrium. Such stress is invisible on the macroscopic scale where the sy…
General up to next-nearest neighbour elasticity of triangular lattices in three dimensions
Cyril Dubus, Ken Sekimoto, Jean-Baptiste Fournier
We establish the most general form of the discrete elasticity of a 2D triangular lattice embedded in three dimensions, taking into account up to next-nearest neighbour interactions…
Internal Stress in a Model Elasto-Plastic Fluid
Takeshi Ooshida, Ken Sekimoto
Plastic materials can carry memory of past mechanical treatment in the form of internal stress. We introduce a natural definition of the vorticity of internal stress in a simple tw…
History Memorized and Recalled upon Glass Transition
Y. Miyamoto, K. Fukao, H. Yamao +1
The memory effect upon glassification is studied in the glass to rubber transition of vulcanized rubber with the strain as a controlling parameter. A phenomenological model is prop…
Discontinuous Crack Fronts of Three-Dimensional Fractures
Yoshimi Tanaka, Koji Fukao, Yoshihisa Miyamoto +1
The relation between fracture surface morphology and the three-dimensional structure of crack fronts is investigated through direct observation of brittle cracks in gels. A key not…
