用电阻应变法测定木材顺纹抗压弹性常数的研究*

Abstract

Abstract:

Three elastic parameters of masson pine were measured by using resistance strain gages.The results of the experiments show that(1) E_L parallel to grain in compression can be measured by strain gages fixed only on radial surface (LR-plane). (2)There is a good agreement between E_L and air-dry density. (3) A good estimate of the compliance can be obtained from the derived equations.

Key words: Wood, Elastic parameters, Resistance strain gages, Compliances
