摘要
随着竹材在建筑行业应用领域日趋广泛,其断裂特性成为安全设计考虑的重要因素。文中简要综述了近年来国内外在竹材断裂韧性测试和断裂机理研究方面的主要进展,并着重强调应借鉴国际生物材料界从生物材料分级结构角度研究材料增韧机制的理念,从宏观、组织和细胞水平及分级界面的角度来定量揭示竹材的增韧机制。
With the should be seriously bamboo fracture tou increasing application of bamboo in the construction, the fracture property of bamboo considered in safety design. This paper overviewed the recent progress in terms of ghness 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.
