The elastostatic axisymmetric problem for a long thick-walled cylinder containing an axisymmetric circumferential internal crack with two claddings is considered. The claddings having different elastic properties than the hollow cylinder are assumed to be bonded to inner and outer wall of the hollow cylinder. The problem is formulated in terms of a singular integral equation of a well known type; the derivative of the crack surface displacement being the density function; using the standard transform technique. By using appropriate quadrature formulas; the integral equation is reduced to a system of linear algebraic equations. This system is solved numerically and the related stress-intensity factors are calculated for the cases of hollow cylinder with two claddings bonded to inner and outer wall of the cylinder; a cladding bonded to inner wall of the cylinder; a cladding bonded to outer wall of the cylinder and no cladding under axial tensile load. The influence of the geometrical configuration; the claddings and internal crack length on the stress-intensity factors is shown graphically. © 2005 Elsevier SAS. All rights reserved;
