Modelling considerations for large deformation impact problems

PDF Version Also Available for Download.

Description

Transport casks used to move spent nuclear fuel between storage locations must be designed for accidental drops which may occur during cask handling. The potential for damage is especially significant for side drops, where deformations of the cask inner cavity are likely to be the most severe. There are various analytical methods available to evaluate the deceleration and deformation of a cask for a postulated side drop, but little test data to support them. In this study, three techniques to determine the damage to a cask resulting from a side drop were compared: the classical closed-form method, the finite element ... continued below

Description

Transport casks used to move spent nuclear fuel between storage locations must be designed for accidental drops which may occur during cask handling. The potential for damage is especially significant for side drops, where deformations of the cask inner cavity are likely to be the most severe. There are various analytical methods available to evaluate the deceleration and deformation of a cask for a postulated side drop, but little test data to support them. In this study, three techniques to determine the damage to a cask resulting from a side drop were compared: the classical closed-form method, the finite element static equivalent method, and the finite element dynamic method. In addition, the effect of the dynamic yield stress chosen for the lead shielding was examined, along with other analytical parameters.
