Abstract
This paper examines the axisymmetnc problem of an external circular crack, which
is located in a fibre-reinforced elastic solid. In contrast to the classical problem
where the surfaces of the crack region are traction free, this paper considers the
situation in which fibres exhibit continuity across the external crack thereby inducing
a displacement dependent traction boundary condition. The influence of the
bridging action on the crack opening mode stress intensity factor at the crack tip,
created by axisymmetnc loading of a doublet of concentrated forces, is examined.
1 Introduction
Unidirectional fibre-reinforced composites consist of a matrix reinforced with a
random or regular network of closely spaced aligned fibres. The elastic stress
analysis of these composites can be performed by idealizing the material
