The Higher Order Axis-Directional Crack-Tip Field for Power FGMs Cylindrical Shell with Reissner's Effect

The theory for cylindrical shell with Reissners is adopted to analyze the axis-directional crack problem for FGMs cylindrical shell by using the asymptotic expansion method. The eigen-solution of the crack-tip fields for the cylindrical shell are obtained. The results are similar to Williams solution for the plane problems in homogeneous materials, and will be of wider application to engineering structures.
