Contact Problem Of Fiber-matrix
In Composites

Abstract
This paper deals with contact problem describing the mechanical behavior
of the interface between fibres and matrix in composite materials. The
interface is considered to be "infinitely" thin and is characterized by conti-
nuity of interfacial tractions and by possible jumps in displacements. The
physical behaviour of the interface is non-convex. The penetration of fiber
into matrix is not allowed. Such an interfacial zone may have been created
either by coating the fibers or it may have developed during the manu-
facturing process due to chemical reactions between the contacting fiber
and matrix materials. In this contribution we start with a definition of
the model describing the transfer of elastic stresses from the matrix to the
fiber. Then, the contact problem is formulated in a manner leading to a
very fast Uzawa's algor
