TAMAYO-MEZA, Pedro et al. Dynamics Study of Processes Fracture and Fiber- Reinforced Materials Delamination. Rev.fac.ing.univ. Antioquia [online]. 2014, n.70, pp.119-131. ISSN 0120-6230.

With the construction of a plane model, a qualitative study was made in order to observe the transactions that are developed during the fracture process and its simulation on different sections of a composite, from the accumulation of the damage stage to the moment when the crack propagates abruptly causing a macro fracture. An algorithm was developed to observe the stress redistribution processes and the compound is simulated including packaging defects of the filaments. During the study of the fracture processes in reinforced composites there are many factors to consider that are interrelated and that have a casual character. The mechanical properties of the fibers and the matrix, the matrix-fiber adherence and the resistance of the interface, all vary with the application of the load. The use of computational methods opens great possibilities for the development of the simulation and the models of the fracture processes.

Keywords : Fracture; interface; delamination; fiber; matrix.
