Model Analysis of Thin Cylindrical Shell with Axial Crack
Model of thin cylindrical shell with axial crack was analyzed by finite element software ANSYS.The change rule of natural frequency and vibration model of different crack lengths were obtained. The influence of the partial vibration to original vibration of shell was analyzed. When the natural frequency of vibration is close to the shell original vibration, the third vibration will appear near the crack.
