|Summary|| For the prevision of delamination a previously defined Damage Meso-Modeling of composite laminates is used. The interlaminar interfacial deterioration as well as the main inner lyer damage mechanisms are included. Attention is focused herein on the modeling of the interlaminar connection as an elastic interfacial and damageable medium. The connection with Fracture Mechanics and the identification on an interface damage model devoted to the delamination prediction is also addressed possibilities and difficulties are discussed. Examples of comparison between simulation and experiments are included.
