TL;DR: In this article, a new computational method based on the equivalent domain integral (EDI) is developed for mode I fracture analysis of orthotropic functionally graded materials (FGMs) subjected to thermal stresses.

TL;DR: In this article, the authors examined the three dimensional surface crack problems in functionally graded coatings subjected to mode I mechanical or transient thermal loading and computed the stress intensity factors by using the displacement correlation technique.

TL;DR: In this article, a coupled problem of crack/contact mechanics in a nonhomogeneous medium is considered and the results are presented for various combinations of friction coefficient, material nonhomogeneity constant and crack length parameters, in addition to contact stresses, the in-plane component of the surface stress and the stress intensity factors at the crack tip.

TL;DR: In this paper, a laterally graded half-plane in sliding frictional contact with a rigid punch of an arbitrary profile is considered and the governing partial differential equations and the boundary conditions of the problem are satisfied through the use of Fourier transformation.

TL;DR: In this paper, an analytical solution based on singular integral equations and a numerical approach based on the enriched finite elements are developed to evaluate the mixed-mode stress intensity factors and the energy release rate under the given mechanical loading conditions.
