摘要
该文以兴安叶松为原料,依据木结构设计规范对国产落叶松动弹性模量和静弹性模量进行研究.采用应力应变片与应力波法分别测定其静态、动态弹性模量,结果表明:静弹性模量是动弹性模量的1.23倍.图2,表4,参9.
This paper, taking Dahurian Larch as the raw material, studies the dynamic and static modulus of elasticity of Dahurian Larch according to the code for design of timber structures. With the method of stress-strain gauge and stress wave,the result shows that the static modulus of elasticity is 1. 23 as much as the dynamic modulus of elasticity. 2figs. ,4tabs. ,9refs.
