SMART has been developed as an environment-friendly reactor that gives freshwater from the sea as well as electric power. This paper presents the modal analysis prior to evaluating the structural safety against the seismic load. A finite element model of the reactor vessel and the internal structures has been simplified and a modal analysis has been performed using ANSYS. The simplified model is composed of beam elements for the reactor vessel and lumped-mass elements for the internal structures.

A split hopkinson bar could be used for obtaining the high strain rate material properties of sheet metals for an autobody. In high speed tensile tests of sheet matals, a new design of a tension split Hopkinson bar apparatus is needed. The design of grips and an anvil length are numerically analyzed with ABAQUS/Explicit for the new apparatus of split Hopkinson bars. From the experiments with the new apparatus, the material properties of SPCEN in the high strain rate state have been acquired and compared with quasi-static experimental results. The material properties of SPCEN as well as other sheet metals in an autobody are indispensible for the analysis of crashworthness. Nevertheless the experiment of sheet metal in the high strain rate state has not been done or reported.
