Energy absorption and optimization of Bi-directional corrugated honeycomb aluminum

To replace wood as the filler material for the impact limiter of the spent nuclear fuel transportation cask, a bi-directional corrugated honeycomb aluminum (BDCHA) was manufactured. First, five materials with different cell thickness/cell size ratios (t0/a) were designed, and compression tests were performed under quasi-static conditions. The results show that the initial peak stress and the plateau stress both increase with the increase of the...
