Structural code benchmarking: impact response resulting from the regulatory nine-meter drop
Sandia National Laboratories' Transportation Technology Center has initiated a program in cooperation with Battelle Pacific Northwest Laboratories (PNL) to benchmark structural codes that are available to the nuclear materials transportation community. The program consists of the following five phases: (1) code inventory and review, (2) development of a cask-like set of problems, (3) multiple independent numerical analyses of the problems, (4) transfer of information, and (5) performance of experiments to obtain data for comparison with the numerical analyses. The benchmark problems were selected to be cask-like and to require simulation of the nine-meter drop condition. Selected problems simulated end and side drop conditions with the more complex corner drop eliminated to reduce the computer costs associated with three-dimensional analysis. The results showed that the codes were in reasonable agreement in simulating gross cask behavior such as impact duration and total deformations. As expected, variability in these parameters increased as the problems progressed from purely elastic behavior to elastic/plastic behavior. In addition, the analyses indicated that the local stresses and strains in high gradient regions are sensitive indicators of code behavior.
