Dynamic Deformations and Stresses in a Circular Cylindrical Shell with Both Ends Clamped Subjected to Translational Excitations at the Base

抄録

In this paper, an exact analysis for the dynamic stresses and deformations in a circular cylindrical shell with both ends clamped subjected to impulsive motions at the clamped end is presented on the basis of Flugge's dynamic shell theory and with use of Laplace transformation. The end motions are prescribed by three kinds of loading functions whose velocity histories in time are half sine, rectangular and exponentially decaying pulses, respectively. In the results, it is shown that the dynamic deformations and stresses are much affected mainly by the velocity histories of the end motions and by the relation between the period of the lowest natural frequency of the cylindrical shell and that of the end motions.
