Abstract :
The higher order asymptotic fields which are similar to the Williams´ solutions of plane crack problems in homogenous materials are obtained by the asymptotic analysis for a crack in functionally graded Reissner´s spherical shell. The results provide a theoretical basis for the numerical analysis, experimental investigation and the engineering application of FGM shell structure.
