EFFECTIVE ELASTIC AND STRENGTH PROPERTIES OF UNIDIRECTIONAL FIBROUS CERAMIC COMPOSITES
Abstract eng: The present paper is concerned with the evaluation of effective properties and macroscopic tensile strengths of unidirectional fibrous composites made of basal fibers bonded to a ceramic matrix. The actual random distribution of fibers in transverse plane is taken into through the application of statistically equivalent periodic unit cell. A simple maximum stress failure criterion, combined with a linear format of traction separation law, is used to track the onset and subsequent gradual evolution of damage in the composite. The resulting macroscopic stress-strain curves are finally examined to define the searched macroscopic strength of the composite needed, e.g. in the meso-scale analysis of plain weave textile composites.
