Fracture Mechanics of Fiber-Reinforced Composites
Quantitative understanding of the parameters which control composite fracture is imperative to the implementation of fail safe design and inspection of critical load bearing structures. For isotropic materials, fracture is essentially controlled by a single parameter, e.g., the fracture toughness or the stress-intensity factor. This one dimensional nature lends itself to experimental quantifica...
متن کاملHomogenization of Fiber Reinforced Brittle Materials: the Intermediate Case
We derive a cohesive fracture model by homogenizing a periodic composite material whose microstructure is characterized by the presence of brittle inclusions in a reticulated unbreakable elastic structure.
متن کاملHomogenization of Fiber Reinforced Brittle Materials: The Extremal Cases
We analyze the behavior of a fragile material reinforced by a reticulated elastic unbreakable structure in the case of antiplane shear. The microscopic geometry of this material is described by means of two small parameters: the period ε of the grid and the ratio δ between the thickness of the fibers and the period ε. We show that the asymptotic behavior as ε → 0 and δ → 0 depends dramatically ...
متن کاملEffect of Fiber Inclination on Crack Bridging Stress in Brittle Fiber Reinforced Brtttle Matrix Composites
THE MECHANICAL behavior of brittle matrix composites is strongly affected by the bridging of cracks by fibers. In random fiber composites, libers can lie at an angle to the crack plane. Under such conditions, the bridging stress for a certain crack opening is governed by various micromcchanisms including fiber debonding, fiber bending and rupture as well as matrix spailing. While fiber debondin...
متن کاملCharacterization and Effects of Fiber Pull-Outs in Hole Quality of Carbon Fiber Reinforced Plastics Composite
Hole quality plays a crucial role in the production of close-tolerance holes utilized in aircraft assembly. Through drilling experiments of carbon fiber-reinforced plastic composites (CFRP), this study investigates the impact of varying drilling feed and speed conditions on fiber pull-out geometries and resulting hole quality parameters. For this study, hole quality parameters include hole size...
