Experimental investigations, recently performed on mixed-mode in concrete emphasize the path-dependency and, inducing localization, are strongly affected by specific phenomena linked to the heterogeneity material such as aggregate interlock. In the framework non-local damage mechanics a new to model cracking by means of a non-local anelastic strain tensor presented. The model able to take into account the induced anisotropy due to cracking, the position, the mean openings and the residual ...... JI. ... .., ........... ..,..., stresses transmitted along the cracks. With reference to experimented paths, some comparisons are in order to check the reliability of the model, and highlight some problems related to the non-local nature of the model.
