Confinement Shear Effect in Fiber Composites

Abstract:

Composites have been playing an increasingly important role in various engineering applications. We examine the confinement shear effect arising in the neighborhood of the fiber-matrix interface in fiber-reinforced materials, which is a problem calling for further investigations. It is well known that the progressive failure process strongly depends on the interfacial transition zone (ITZ). Thus, we take the studied material as three-phased, i.e. fiber, matrix and interface in between. The generalized beam (GB) lattice model is adopted to simulate the compressive failure behavior of a representative volume element with one fiber included. Numerical results are provided to explain the confinement shear effect during the progressive failure process in specimens with various fiber-matrix properties, fiber orientations and distributions.
