Benchmark calculations for mechanical stresses upon a transport cask Original Research Article

In this paper, benchmark calculations are carried out using the FEM code ADINA. Three drop tests with a DCI cask carried out in Japan are investigated. The drop orientations comprise the 9 m drop with impact flat onto the cylindrical shell of the shock absorbers at the top and bottom part as well as the 1 m drop with impact of the bar in the center of the cylinder wall. Calculated results are compared to the experimental ones. It is found that the calculations meet the measurements conservatively.
