We show that discrete models of atoms subject to nearest-neighbour non-linear interactions approximate continua allowing for softening and fracture. A detailed study of local minima and stationary points is carried out. Scale effects are discussed.

Abstract
We show that discrete models of atoms subject to nearest-neighbour non-linear interactions approximate continua allowing for softening and fracture. A detailed study of local minima and stationary points is carried out. Scale effects are discussed.File in questo prodotto:
