Abstract:In this paper, the elastic analysis is performed for isotropic materials containing layered elliptical inclusion under In-plane loads at infinity. This analysis shows importance that inclusion and matrix are influenced by interface. In this analysis, general solutions of this problem are obtained by using complex function and confomal function. Some numerical results are shown by graphical representation. And we calculate stress intensity-factor of Mode ‡T and Mode ‡U of slit-crack in the layered elliptic inclusion under In-plane loads.

Key Words:Elliptical inclusion, In-plane loads, Confomal function, Complex analytical solutions, Stress-Intensity-Factor
