| Abstract: | With the increasing application of bamboo in the construction, the fracture property of bamboo should be seriously considered in safety design. This paper overviewed the recent progress in terms of bamboo fracture toughness test and fracture mechanism at home and abroad. What is more, it was specially emphasized that it should investigate the toughening mechanism of bamboo timber based on its hierarchical structure from macro to tissue, cell and sub-cellular level as well as its hierarchical interface by learning the concept used by international biological materials community to study the toughening mechanism from the perspective of hierarchical architecture. |
