【Abstract】 In this paper, the effect of circumferential cracks on the dynamic characteristics of Shell of revolution is calculated by means of the model of zero dimension element with crack (i. e., the element length in the direction of perpendicular to crack is zero). The experiments on shells of revolution with a circumferential through-crack have been done. The calculated results by using the model are in very good agreement with the experimental results.更多还原
