Interaction between interfacial and sub-interfacial cracks in a composite media – Revisited

Abstract

The plane strain problem of determining stress intensity factors and stress magnification factors for an interfacial Griffith crack situated at the interface of two bonded dissimilar orthotropic media having sub-interfacial Griffith crack is considered. The problem is reduced to the solution of two pair of simultaneous singular integral equations which are finally been solved by using Jacobi polynomials. The propagation of interfacial crack through amplification and shielding factors are shown graphically for different particular cases. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
