Most of the methods to detect a crack in beam-like structures are based on linear one-dimensionalmodels. Evidently these approaches are not applicable to structures such as beams or arcs with an open crack or a breathing crack without or with contact. The present study deals with bi and tri-dimensional models to handle the statics or dynamics of an structural element (with an arbitrary shape) with a transverse breathing crack. The crack is simulated as a notch with a unilateral Signorini’s contact model.
