Influence of Dynamic Effects Associated with the Breaking and Delamination of Fibers in Composites, and Interaction of the Micromechanisms of Fracture

The development of the fracture in composites reinforced with brittle fibers, it is generally accompanied by the rupture of single fibers, the exfoliation of broken filaments of the matrix, the collapse of surrounding filaments due to localized overloading, etc. The study of the dynamic effects, related with the stress distribution during rupture of fibers and their separation of the matrix, gives new aspects about the interrelation of these micromechanisms of fracture and allow the development of algorithms that make possible their computer simulation.
