Abstract

Generally, to evaluate impact analysis in the event of an accident, the mechanical properties of a shock absorbent material such as wood have been used at room temperature. However, there is potential for the impact acceleration to increase due to softening of the wood with the increase of temperature up to a locking-up point. In this study, three wood species (oak, fir-ply and balsa) were selected, and a series of static and impact material tests performed to investigate the temperature dependence and strain rate effect on the compressive properties. Consequently, the need to take these influences into consideration in cask design was confirmed due to the decline in impact energy absorption performance beyond 50?C.
