Analytical Modeling of Micromechanical Stress Variations in Continuos Fiber-Reinforced Composites,sional mechanical and hygrothermal loading are investigated analytically. An elasticity solution is developed for the case in which the fibers are arranged in a regular, periodic array. The model accounts for fiber-fiber interactions, multiple interphases, cylindrically-orthotropic and temperature-

Micromechanics as a Basis for Damage Mechanics,olume averaging of state variables in the representative volume element. These concepts are first reviewed for composites composed of linear elastic constituents and then extended to include the case of composites with time dependent microcracks. A brief review is then given of recent micromechanics

Micromechanics for Performance Simulation, composite materials. Moreover, if one wishes to describe the degradation of strength over long periods of time (say, during the engineering use of such materials) this fundamental weakness precludes definitive systematic use of mechanics for that purpose as well..The use of various local mechanics

On Statistical Micromechanical Theories for Brittle Solids with Interacting Microcracks,ineers, and have been the subject of many investigations. See Krajcinovic (1989) for a literature review on damage mechanics. For brittle materials, in particular, microcracks often control overall deformation and failure mechanisms. To date, the only exact results derived for microcrack-weakened br

Fibre Composites: Mesomechanics and Mesostructures,aterial which sometimes leads to unexpected property variations which could not be predicted directly from micromechanical considerations. In addition, in the composites themselves, a mesostructure can be observed, as well as a microstructure. A typical example of this is the fibre waviness that occ

Deformation of a Meta-Ceramic Composite with a Crystal Matrix: Reinforcement Distribution Effects,astic-plastic constitutive relation that allows for elastic anisotropy and slip along three planar slip systems. Plane strain analyses are carried out for various whisker distributions at a fixed whisker volume fraction. For an elastic matrix, the effect of distribution on the aggregate stiffness ca

An Energy Based Model for the Influence of the Fibre-Matrix Interface Strength on the Interlaminar and the fracture toughness of carbon-epoxy composites, carbon fibres with four different oxidative treatment levels were used. Mode I tests were performed using DCB-tests. Acoustic emission was used to determine the initiation of the delamination from the precrack. Results show a dramatic increase o
