Buckling analysis on finite-sized shell structures

The theoretical analysis of finite element method for buckling phenomenon to finite-sized shell structure is first introduced. Then, a real application using a probe for detecting the pressure inside turboprops is analyzed thoroughly with ANSYS10.0, including section profile, dimensions, and local characteristics. Based on the solved results, several rules between critical load and influence factors are obtained, which would be helpful for similar structures design and application. Finally, several useful conclusions about the best profile and ratio between dimensions are obtained.
