Abstract :
The testing experiments to healthy poplar and larch logs samplings were conducted by using Arbotom stress wave testing instrument and universal mechanics testing machine. The relationships between dynamic modulus of elasticity of stress wave E1, E2, E3 and compression properties were studied in the two logs samplings. The results indicated that, in the poplar and larch logs samplings, the dynamic modulus of elasticity of stress wave E1, E2, E3 all had certain linear correlation with compression strength and modulus of elasticity in compression.
