Periodic set of the interface cracks with contact zones in an anisotropic bimaterial subjected to a uniform tension-shear loading

A closed form solution to the plane problem of the theory of elasticity for an infinite anisotropic bimaterial space (plane) with a periodic set of the interface cracks with frictionless contact zones near its tips is obtained. By means of the complex function presentation the problem is reduced to the combined Dirichlet-Riemann boundary value problem for a sectionally holomorphic function and solved exactly. The equations for the determination of the contact zone lengths as well as the closed form expressions for the stress intensity factors are carried out. The variation of the mentioned values with respect to the distance between the cracks is illustrated in table and graphical forms. (c) 2006 Elsevier Ltd. All rights reserved.
