| 摘 要： | 按照传统的强度理论，对干燥后用作建筑或农村房舍结构的木材进行校核和设计时，常忽视木材内部存在的初始干燥裂纹。本文阐述了木材的正交各向异性特征和其干燥后裂纹，以及裂纹时木材强度的影响，并结合木材正交各向特征时其裂纹与断裂力学行为的研究方法提出了初步的构想。 |
| 关 键 词： | 木材 干燥 裂纹 断裂 正交各向异性特征 强度 |

| Abstract: | According to conventional strength theory, the initial cracks in wood drying were always neglected when dried wood was directly used as architectural or rural farmhouse configuration materials in the past. In this paper, the authors elaborated the cracks in wood drying, wood ortho anisotropic characteristics and crack influence on wood strength. Some preliminary ideas were discussed on researching wood crack and fracture behavior with wood ortho anisotropic characteristics. |
