• The paper is concerned with the linear dynamic response of arbitrary shells of revolution to time-dependent loads. The dynamic response problems of shells of revolution to time-dependent loads are important in engineering design. The studies on the dynamic response of axisymmetrical shells, however, are almost limited to the simple geometries such cylindrical shells and spherical shells. Then in this paper the authors derive the basic differential equations on the dynamic response of arbitrary axisymmetrical shells under time-dependent loads by extending Budiansky's method based on Sanders' shell theory. In the numerical analysis of this problem the spatial derivatives are represented by usual finite difference forms and the acceleration terms are treated with the backward difference formula proposed by Houbolt. Three numerical examples - a cylinder under a semi-sinusoidal pulse, a cylinder and a pressure vessel under a blast loading are presented.
