| 摘 要： | 以毛竹(Phyllostachs pubescens)为对象,对竹材应力松弛规律进行了实验研究,分析了不同温度及不同含水率对竹材横纹压缩的应力松弛特性的影响,建立了描述竹材横纹压缩应力松弛模型。实验表明,竹材横纹压缩应力松弛与含水率、温度、应变水平密切相关,随着温度的升高和含水率的增加,竹材的应力松弛速率增大,应力松弛时间缩短。

| Abstract: | The stress relaxation characteristic of Moso bamboo(Phyllostachys pubescens)samples with different moisture contents in transverse compression under different temperatures was studied, and the stress relaxation element model of bamboo in transverse compression was obtained.The result showed that the stress relaxation of bamboo is in high correlation with the temperature,the moisture content and the strain level.The increase of the temperature and the moisture content would make the stress relaxation speed increased and the stress relaxation time reduced. |
