冻材主方向弹性模量微观力学求解理论

采用复合材料力学的微观力学理论，在横观各向同性的假设下，提出了一种计算冻材主方向弹性模量的理论求解方法。应用提出的理论，可以根据纤维素、木质素、细胞直径和冻结的程度。求出冻结状态下木材的主方向弹性模量。为木材力学中的冻材分析提出了一个新的解决方法，并且可以定量解释木材冻结后硬度与弹性模量提高的原因。

Microscopic Dynamic Theory Solution Method of Freezing Wood Elastic Modulus in Main Direction

Using the microscopic dynamic theory of composite material dynamics, under the hypothesis of cross direction isotropy, the authors put forward a theoretical solution method which counts freezing wood elastic modulus in main direction, According to the cellulose. lignin. cell diameter and the freezing degree the wood elasticity modulus in the main direction can be got, This theory can quantitatively explicate the reason of wood rigidity and elasticity modulus increase.
