电阻应变法测定杉木弹性常数的研究

Study on Determining the Elastic Constants of Wood of Cunninghamia lanceolata by Means of Electric Resistance Strain Gauges

测试杉木的弹性常数 ,研究木材采用正交各向异性体模型的限制条件。结果表明 ,可以采用电阻应变法以单轴压缩试件测定木材弹性常数 ;

The elastic constants of wood of Cunninghamia lanceolata was determined and the limits of orthotropic model adopted for wood was studied. The results showed that the elastic constants of wood could be determined by means of electric resistance strain gauges,and the constants was satisfied to the limits of orthotropic.
