Each of the hypothetical accident test cases for the 9977 prototypes was included in the battery of finite element structural analyses performed for the package. Comparison of the experimental and analytical results provides a means of confirming that the analytical model correctly represents the physical behavior of the package. The ability of the analytical model to correctly predict the performance of the foam overpack material for the crush test is of particular interest. The dissipation of energy in the crushing process determines the deceleration of the package upon impact and the duration of the impact. In addition, if the analytical model correctly models the foam behavior., the predicted deformation of the package will match that measured on the test articles. This study compares the impact acceleration and impact duration for the test articles with those predicted by the analyses. In addition, the deformations of the test packages with the analytical predictions are compared.
