木材弹性及木材干燥应力——Ⅰ.木材弹性参数的理论和测试

<正>本文在对真实木材作理想化假设之后,论述了木材弹性参数的理论和测试方法。提出弹性参数的含水率系数具有和参数一样的对称性质。测定水曲柳弹性参数的实验结果证明这一理想化假设是正确的,也表明电测法是一种比较可靠的测试手段。

ELASTICITY AND DRYING STRESSES OF WOODI. THEORY AND DETERMINATION OF ELASTIC PARAMETERS OF WOOD

Theory and method of determination of elastic parameters of wood are here presented, where the wood was supposed to be in the ideal mechanical model. It is pointed out that the moisture content coefficients of the elastic parameters have the same property of symmetry as the parameters. The tesults of the determination of the elastic patameters of Manchurian ash (Fraxinus mandshurica) wood proved that the supposition of the ideal mechanical model is right and that electrical measuring method is a reliable means of determination.
