| Abstract: | in this paper the dynamic stress intensity factor of thick walled cylinder is computed. The finite element method for computing dynamic stress intensity factor is studied and reasonable computational schemes are provided. The superposition integral method is presented to compute dynamic stress intensity factor of thick-walled cylinder, which is convenient for computing dynamic stress intensity factors under the conditions of various dynamic inner pressures. |
