Abstract:
Several cases of the dynamic stability problem for cylinders are solved explicitly. Combinations of the static and periodic radial and axial loads are considered. The regions of instability and stability are established directly in terms of the geometry of the cylinder, load intensity, and frequency. All the numerical results obtained here tend to indicate that a cylinder designed according to the static buckling load can withstand an additional periodic load. It was found that the ratio of additional periodic load to the static buckling load was greater for a thin cylinder than for a thicker cylinder of the same radius. It was also found that the resistance of a cylinder to loads in excess of the static buckling load increases with increasing frequency of loading. Author
