Abstract

In this study the problem of FGM coatings with an interface crack subjected to a mechanically or thermally induced compressive load parallel to the free surface is considered. First by using a nonlinear continuum theory the problem is reduced to an eigenvalue problem and the buckling instability load is evaluated analytically. The postbuckling problem is then examined numerically. The strain energy release rate and the stress intensity factors are directly calculated from special enriched crack tip elements.
