Original Abstract

The methods based on the properties of the two-state integrals allow one to calculate the amplitude of singular and the other terms of the Williams asymptotic expansion. The paper is focused on the use of the Y-integral, whose application is conditioned by the knowledge of the socalled auxiliary solution of the solved problem. On the other hand, the Y-integral can be applied to the analysis of the problems with various geometries, e.g. the analysis of the bi-material notches. The application of the Y-integral can be also extended to the matched asymptotic procedure, which allows one to predict the behavior of the cracked notches or following crack growth near the bimaterial interfaces.

Keywords

Orthotropic bi-material notch, two-state integral, psi-integral, matched asymptotic expansion, Betti's reciprocity theorem
