TLDR
In this article, the authors investigated the dynamic response of a cellular sandwich core material, balsa wood, over its entire density spectrum ranging from 55 to 380 kg/m 3, and found that while the initial failure stress is very sensitive to the rate of loading, plateau (crushing) stress remains unaffected by the strain rate.About:
