Study On the Correlation between Mechanical Characteristics and Non-destructive Testing of Stress Wave in Larch Logs

摘要

The testing experiments to healthy larch logs samplings whose diameter scopes are in 5-12cm and the length respectively are 10cm and 30cm were conducted by using Arbotom stress wave testing instrument and universal mechanics testing machine．The relationships between dynamic modulus of elasticity of stress wave and MOE，between MOR and MOE were all studied in the larch logs samplings．The results indicated that,in the two larch logs samplings．the dynamic modulus of elasticitv of stress wave had positive linear correlation with MOE．Moreover．MOR also had a good linear correlation with MOE．
