The present chapter aims at providing a generalized model for studying crack in layered materials. This study has been performed using EFGM. The results and plots obtained are compared and validated with standard FEM. EFGM significantly reduces the computational time and engineering effort compared to FEM. J-Integral is used to calculate SIFs and a novel Jump Function approach is used to detect the change in material properties in coatings. The crack is provided at centre of substrate and its variations with respect to SIFs are plotted. The Weak discontinuity that is material interface has been successfully detected along with strong discontinuity that is crack using intrinsic enrichment in one domain.
