A nonlocal F.E. model for the paradigmatic case of monodimensional elastic- fracturing (damaging) materials is presented, which can be proved to converge to the dis- continuous solution of Fracture Mechanics, when a characteristic parameter of nonlocality tends to zero. The efficiency of such a model is assessed and relationships with existing models are discussed in some details.

Abstract
A nonlocal F.E. model for the paradigmatic case of monodimensional elastic- fracturing (damaging) materials is presented, which can be proved to converge to the dis- continuous solution of Fracture Mechanics, when a characteristic parameter of nonlocality tends to zero. The efficiency of such a model is assessed and relationships with existing models are discussed in some details.File in questo prodotto:
