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。
The micromechanics theory of composite mechanics is used under the assumption of transverse isotropy. A method to calculate the principal elastic moduli of frozen wood was proposed. Applying the proposed theory, the principal direction modulus of elasticity of the wood in freezing condition can be determined according to the degree of cellulose, lignin, cell diameter and freezing. A new solution for the analysis of frozen material in wood mechanics is proposed. And the reasons for the increase of hardness and elastic modulus after wood freezing can be quantitatively explained.
