摘要：

以玛瑙省藤材和钩叶藤材为研究对象,分析了2种藤材的弯曲蠕变性能。结果表明:当应力分别为弯曲破坏荷载的30%、50%、70%时,随着应力的升高,2种藤材的蠕变变形显著增加;所产生的蠕变变形与应力水平不成比例增加,钩叶藤材和玛瑙省藤材的蠕变过程都是非线性的;藤材种类对棕榈藤材的瞬时弹性变形影响显著,且玛瑙省藤材的瞬时弹性变形明显大于钩叶藤材。

摘要：

In this paper,the bending creep behavior of Plectocomia pierreana and Calamus manan were studied. The results showed that the creep deformation of two kinds of rattan cane increased significantly with the increase of stress as the stresses were 30%,50% and 70% of the bending failure loads,respectively. The deformation increased by that of stress level were disproportional. The creep behaviors of P. pierreana and C. manan were nonlinear. In addition to the instantaneous elastic deformation of C. manan was significantly larger than that of the P. pierreana,the species of rattan was a remarkable effect on creep behaviors.
