Stochastic structural interface defects in fiber composites

this paper the new idea of homogenization of stochastic interface structural defects in the matrix of a fiber composite, recently proposed by the first author, is extended to the contact zones of both components. The physical mechanism of the occurrence of interface defects is described and diflerent versions of location of these defects on fiber-matrix boundary are tested using the stochastic finite element method (SFEM). Two first moments of the displacement random fields are compukd and a new SFEM formulation for such problems is proposed. Copyright 0 1996 Elsevier Science Ltd.
