Thermoelastic Dynamics of Rods, Thin Shells, and Solid Spheres

The purpose of this study is the determination of the dynamic movements and stresses in fuel structures when subjected to a rapid temperature pulse. The maximum expansion and stress produced in any of these elements is proportional to the magnitude of the temperature pulse, but also depends upon the ratio of the temperature pulse period to the natural period of oscillation. Parametric curves are plotted which show the dynamic expansions and stresses in these elements when they are subjected to temperature pulses of varying duration.
