Description The description of crack propagation in structural materials is still a great challenge because the discontinuous nature of the phenomena conflicts with the underlying mathematical structure of classical continuum mechanics. Recently a new non-local continuum theory has been proposed, Peridynamics, with the specific goal to overcome the limitations of the classical theory. Peridynamics is based on integral equations and does not make use of spatial differentiation, for these reasons it is better suited to describe problems affected by discontinuities. The paper presents a series of applications of peridynamics-based computational methods to the solution of static and dynamic structural problems.
