Abstract
In this study, eigenvalue buckling analysis for cracked functionally graded cylindrical shells is performed using eight noded degenerated shell elements in the framework of the extended finite element method. First, validity and efficiency of the proposed method in comparison with available results are examined and then the approach is utilized for examining cracked FGM cylindrical shells subjected to different loading conditions, including axial compression, axial tension and combined internal pressure and axial compression. Also, the effects of various parameters such as crack length and angle, gradient index of the material, aspect ratio of the cylinder and internal pressure on the buckling behavior are extensively investigated.
