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。 As bamboo is becoming more widely used in the construction industry, its fracture characteristics have become an important factor in safety design considerations. In this paper, the recent advances in the research on the fracture toughness and fracture mechanism of bamboo at home and abroad are briefly reviewed. The concept of toughening mechanism of materials from the perspective of the hierarchical structure of biomaterials should be drawn on from the international community of biomaterials. Cell level and grading interface angle to quantitatively reveal the toughening mechanism of bamboo.
