摘要

摘要本研究旨在利用非破坏性纵向振动声学方法估算柯木的MOE,以检验其可靠性。获得了三棵B.augustifolia树,并采集了的样品用于木材弹性的动态和静态弯曲测试。在烘箱干燥后,样品在测试前储存一个月。获得的B.augustifolia木材的动态(dMOE)和静态弹性模量(sMOE)的平均值为6.908 ± 0.7525 GPa和6.9148 ± 0.5870 GPa。所做的分析显示,两种方法的值之间没有显著差异,而回归模型的决定系数为0.65,具有显著性。在dMOE和dMOE之间观察到0.81的强相关性。同时,木材密度与dMOE和dMOE的相关性分别为0.73和0.50。所使用的声学方法被认为是确定木材MOE的可靠方法。

Estimation of modulus of elasticity of Boscia angustifolia wood using longitudinal vibration acoustic method
ABSTRACT This study aimed at estimating MOE of Boscia augustifolia wood using non-destructive longitudinal vibration acoustic method with the view to examining its reliability. Three trees of B. augustifolia were obtained, and samples of were collected for dynamic and static bending testing of the wood’s elasticity. The samples were stored for a month prior testing after oven dried. Mean values of dynamic (dMOE) and static modulus of elasticity (sMOE) of B. augustifolia wood obtained were 6.908 ± 0.7525 GPa and 6.9148 ± 0.5870 GPa, respectively. Analysis done showed no significant difference between the values from the two methods while regression model was significant with 0.65 coefficient of determination. Strong correlation of 0.81 was observed between the dMOE and sMOE. Meanwhile, wood density had a correlation of 0.73 and 0.50 with dMOE and sMOE respectively. The acoustic method used was considered reliable for determining MOE of the wood.
