| 摘 要： | 以毛竹为对象,研究了在不同应力水平及不同温度、含水率下竹材横纹压缩的蠕变特性。实验结果表明,竹材横纹压缩蠕变组分与含水率、温度、应力水平密切相关;当压应力在屈服极限以下时,竹材横纹压缩蠕变的三种组分总量均与压应力、温度和含水率成正比,但温度和含水率的升高会使弹性组分的比量下降、粘弹性和粘性组分的比量增大。

| Abstract: | This paper studied the rheological characteristics of Moso bamboo(Phyllostachys heterocycla var.pubescens) in transverse compression under different levels of temperature,moisture and stress.The results showed that the creep of bamboo was highly correlated with temperature,moisture content and stress level.When compressed stress is under yield stress,three components of creep(elasticity,visco-elastcity,viscosity) were proportional to compressed stress,temperature and moisture content.But the increase of temperature and moisture content would decrease the elasticity component proportion and increase the visco-elasticity and the viscosity component proportion. |
