Abstract: | An axisymmetrical fiber-matrix cylindrical model with a circumferential crack in the matrix of finite diameter is formulated
within elastostatic scope. The problem is considered by means of integral transforms and a singular integral equation with
a dominant generalized Cauchy kernel is obtained. Following the numerical solution technique developed by Erdogan, Gupta and
Cook, the singular integral equation is reduced to a system of linear equations. By solving the linear equations, stress intensity
factors associated with the crack length and the material properties are calculated and discussed. The solutions presented
in this study are found to be general, including the solutions as special cases of the present formulation for a homogeneous
solid cylindrical bar and a thick-walled shell with an outer circumferential crack.
