Abstract

Acacia auriculiformis has been adopted in Benin as an energy wood through the firewood project since 1985. Increasingly, people use it as timber due to scarcity of conventional species and its availability while its physical and mechanical parameters are little known. It was determined the percentage of heartwood, density, modulus of elasticity and shear modulus of this wood in order to appreciate its current use as timber and to estimate its exploitable age. 18 trees of 5; 8-10 and 20 years were sampled from plantations of Sèmè, Pahou and Itchèdè-Toffo. It appears that from 8 years onwards, the percentage of Acacia auriculiformis heartwood is above 70%. With medium module of elasticity, the density and the mechanical parameters of Acacia auriculiformis have low variability between 8 and 20 years. Compared to species conventionally used, its current use is justified and suggest an exploitability age of 15 years to be refined.

在贝宁用作木材的金合欢的物理和机械特性
自1985年以来,贝宁通过木柴项目采用金合欢作为能源木材。由于常规树种的稀缺性和可获得性,人们越来越多地将其用作木材,而其物理和机械参数却鲜为人知。测定了该木材的心材百分比、密度、弹性模量和剪切模量,以便了解其目前作为木材的使用情况,并估计其可利用年龄。18棵5棵;从Sèmè、Pahou和itch d - toffo人工林取样8-10年和20年。似乎从8年以后,金合欢心材的比例在70%以上。金合欢的密度和力学参数在8 ~ 20年之间具有较低的变异性,弹性模量中等。与传统使用的物种相比,其目前的使用是合理的,并建议将其开发年龄提高到15年。收稿05-04-2021修订20-05-2021接受21-05-2021发布16-06-2021

期刊介绍: IJCMSSE is a refereed international journal that aims to provide a blend of theoretical and applied study of computational materials science and surface engineering. The scope of IJCMSSE original scientific papers that describe computer methods of modelling, simulation, and prediction for designing materials and structures at all length scales. The Editors-in-Chief of IJCMSSE encourage the submission of fundamental and interdisciplinary contributions on materials science and engineering, surface engineering and computational methods of modelling, simulation, and prediction. Papers published in IJCMSSE involve the solution of current problems, in which it is necessary to apply computational materials science and surface engineering methods for solving relevant engineering problems.
