采用双悬臂梁和三点端部切口弯曲试验方法，研究了实木的Mode-I和Mode-II阻力曲线，并提出了一种新的数据处理方法。在所提出的方法中，载荷-挠度顺应性沿着加载线，并在另一个点在测试样品进行了测量，阻力曲线确定使用这些顺应性。此外，阻力曲线进行了比较，从四个传统的数据处理方法确定。从所提出的方法确定的阻力曲线往往是一致的，使用其他方法确定的。所提出的方法可以方便，简单地确定阻力曲线，同时减少了传统的数据处理方法的缺点，因此，它是一个很有前途的候选人来拟合实木的阻力曲线。
Double cantilever beam and three-point end-notched flexure tests of solid wood were performed, and the Mode-I and Mode-II resistance curves were characterised by a novel data reduction method proposed in this study. In the proposed method, the load–deflection compliance along the loading line and that at another point in the test sample were measured; the resistance curve was determined using these compliances. Additionally, the resistance curves were compared with those determined from four conventional data reduction methods. The resistance curves determined from the proposed method were often consistent with those determined using the other methods. The proposed method enables an easy and simple determination of the resistance curve while reducing the disadvantages in conventional data reduction methods; therefore, it is a promising candidate to characterise the resistance curve of solid wood.
