Use of the LLNL 40 kV electric gun to study the shock response of 21-6-9 stainless steel

Description: Exploding foil-flyer plate (''electric gun'') methods have been used to shock 21-6-9 stainless steel over a wide range of shock pulse amplitudes (20 to 53 GPa) and durations (10 to 70 ns). Dislocation generation and twinning have been studied in recovered specimens with the results providing support for the concept of finite rate plastic processes. 24 refs., 6 figs., 1 tab.

Dipole strength functions in the actinide mass region

Description: We have calculated a number of neutron- and photon-induced reactions for the actinide nuclei /sup 232/Th, /sup 238/U, and /sup 237/Np. By fitting average resonance capture (ARC) measurements and total neutron capture data, we deduced absolute dipole strength functions for /sup 233/Th and /sup 239/U. We have found that the M1/E1 ratio is the same as in the /sup 176/Lu case, but the total transition strength was larger by about 27%. 17 refs., 4 figs., 1 tab.

Summary of Deflections from Fully Assembled EC Structure Finite Element Model

Description: The purpose of this note is to summarize the deflections in the fully assembled EC OH and MH module arrays as calculated by a superelement finite element model. These results are for the case where the OH modules are fully connected at four locations on the inner radius and four locations on the outer radius. Both the OH and MH modules are modeled as skins and endplates (and in the case of OH, internal structural plates) only. The OH module has a skin thickness of 1/16-in. Fig. 1 shows the full… more
