A solution for the local plane strain problems using elliptic integrals of Cauchy type

Abstract

We consider a parallel fiber‐reinforced periodic elastic composite that present an imperfect contact of spring type between the fiber and the matrix. We use the elliptic integral of Cauchy type for solving the plane strain local problems that arise from the asymptotic homogenization method. Several general conditions are assumed, which include that the fibers are disposed of arbitrary manner in the local cell, that all fibers present contact perfect with different constants of imperfection, and that their cross section is a smooth closed arbitrary curve. We find that there are infinity solutions for these problems, and we find relations between these solutions and effective coefficients of the composite. Finally, we obtain analytic formulae for the circular fiber case and show some numerical examples. Copyright © 2016 John Wiley & Sons, Ltd.

A solution for antiplane‐strain local problems using elliptic integrals of Cauchy type

“…Given the widespread use of the composites in the industry, physicists, mathematicians and scientists in general have been interested to find effective properties of this type of materials . Recently, we solved the plane‐strain local problems that arise from the asymptotic homogenization method of a periodic composite using a novel technique based on elliptic integrals of Cauchy type . In this work, we deal with parallel fiber‐reinforced periodic elastic composites with transversely isotropic phases.…”
