Description
Summary:The anti-plane displacement discontinuity method is applied to establish the Fredholm integral equation of the first kind for the orthotropic Functionally Graded Material (FGM) coatings subjected to static shear load. The Young's modulus is assumed to vary exponentially through the thickness while the Poisson's ratio is constant. The fundamental solution of anti-plane displacement discontinuity are derived for orthotropic FGM coating with isotropic substrate. The stress intensity factors are obtained directly from the coefficients of the Chebyshev polynomials.
