论述了木材蠕变特性研究的理论与方法,分析了目前木材学术界广泛使用的挠度测量法在获取木材蠕变特性过程中存在的不足,同时根据流变学理论关于蠕变柔量的定义,给出了通过应变测量获取木材蠕变特性的原理和方法。用电测法研究木材的蠕变特性,较目前所用的挠度测试法具有概念严谨、手段先进、实验精度高、效率高等特点。
The theory and method of studying the creep characteristics of wood are discussed. At the same time, the definition of creep compliance is analyzed according to rheological theory. At the same time, The principle and method of obtaining creep characteristics of wood through strain measurement are given. Using electrical method to study the creep characteristics of wood, compared with the current deflection testing method has the concept of rigorous, advanced means, high precision experiment, high efficiency and so on.
