Stress Intensity Factors for a Transverse Crack in Two Half-Planes Bonded by an Infinite Layer

Abstract

The tension problem for a transverse crack in the two half-planes bonded by an infinite layer is studied. The body force method is used to analyze the problem. Based on the numerical results, the effects of crack size, layer width and the material properties of the composite on the stress intensity factor are discussed. The approximation formula for a crack normal to the bond lines is also given.
