摘要: <正>研究了木材顺纹抗拉弹性模量的测定方法,着重分析了加载速度对木材顺纹抗拉弹性模量测定的影响。结果表明:(1)可以采用应变计式引伸仪来测定木材顺纹抗拉弹性模量;(2)加载速度为1.0mm/min较为合理。

Abstract: Testing method of wed modulus of elasticity (MOE)in tension parallel to grain was studied.Influence of loading speed on MOE in tension parallel to grain was analysized.The resultsshowed,(l)The strain gauges attached to Shimadzu Universal Testing Mechine can be used to measure MOE of wed 4 (2)The proper loading speed is 1. 0 mm/min.
