| 摘要: |
| 为了探讨确定木材蠕变特性的常数的方法,用应变测试方法代替相关文献的挠度测试方法对试件进行试验.结果获得木材稳定蠕变阶段内的木材蠕变曲线,测取3个常数:J0、Z0、∑Ji即足以说明材料的蠕变特性.简化了实验,使木材蠕变特性的工程评价变得十分便捷. |

| Abstract: |
| To probe into a method for determining the constants of creeping properties of wood, the strain gauging method is employed in the test of test-pieces instead of the flexibility method in the relevant references. The creeping curve is obtained in the stage of stable creeping of wood. Three constants, J0、Z0、∑JI,are measured to explain the creeping properties of the test-pieces. The determination is simplified and is helpful to the evaluation of creeping properties of wood in engineering. |
