Abstract

The results of dynamic compression tests of aspen under elevated temperature up to +60°C are presented. The tests were carried out based on the Kolsky method using the split Hopkinson pressure bar. To study the anisotropy of properties, aspen samples were fabricated and tested by cutting along and across the fibers direction. Dynamic stress-strain curves were obtained as well as the average values of modulus of active loading sites. The greatest steepness of the loading branches and the highest breaking stresses are observed for the samples loaded along the fiber direction, while the smallest values are noted under loading across the fiber direction. Also the effect of elevated temperature on strength and deformation properties of aspen is estimated.

高温下木材性能的研究

介绍了白杨在+60℃高温下的动态压缩试验结果。试验基于Kolsky法，采用分离式霍普金森压杆进行。为了研究其性能的各向异性，制备了杨木样品，并通过沿纤维方向和沿纤维方向切割进行了测试。得到了主动加载部位的动态应力-应变曲线和模量平均值。在沿纤维方向加载的试样中，观察到最大的陡峭度和最大的断裂应力，而在沿纤维方向加载的试样中，观察到最小的值。并分析了高温对杨木强度和变形性能的影响。
