Crynodeb

We consider the perturbation problem of a Mode III interfacial crack. The perturbation is of geometrical type and can be both perturbation of the crack faces and perturbation of the interface, which can deviate from the initial straight line configuration. Asymptotic formulae are derived for the first-order perturbation of the stress intensity factor. It is shown that, due to the unsymmetrical nature of the problem, the Mode III skew-symmetric weight function derived in Piccolroaz et al. (2009) is essential for the derivation of the correct asymptotic formulae. To illustrate the method, we present the numerical results for different geometrical perturbations of a half-plane interfacial crack in an infinite bimaterial structure.
