by Mohamed Jebahi (Author), Frédéric Dau (Author), Jean-Luc Charles (Author), Ivan Iordanoff (Author)
Complex behavior models (plasticity, crack, visco-elascticity) are
facing several theoretical difficulties in determining the behavior law
at the continuous (macroscopic) scale. When homogenization fails to give
the right behavior law, a solution is to simulate the material at a
mesoscale using the discrete element model (DEM) in order to directly
simulate a set of discrete properties that are responsible for the
macroscopic behavior. Originally, the discrete element model was
developed for granular material.
This book, the second in the
Discrete Element Model and Simulation of Continuous Materials Behavior
set of books, shows how to choose the adequate coupling parameters to
avoid spurious wave reflection and to allow the passage of all the
dynamic information both from the fine to the coarse model and vice
versa. The authors demonstrate the coupling method to simulate a highly
nonlinear dynamical problem: the laser shock processing of silica glass.
