Abstract

Drop impact behaviors of the cask using rigid polyurethane foams (R-PUF) as shock absorbing material were investigated by experiments and numerical simulations. To investigate the shock absorbing capability of R-PUF, side drop tests of a 1/10 scale cask model were carried out. Results obtained by side drop tests suggested that R-PUF worked well as shock absorbing materials, and would be useful for impact limiter of large transportation casks.
