ULTRASONIC WAVE PARAMETER CHANGES DURING PROPAGATION THROUGH POPLAR AND SPRUCE REACTION WOOD
Ultrasonic tests were performed in the main directions at 300 kHz in poplar and spruce reaction wood and normal wood. The experiments were conducted on 2 x 2 x 10 cm3 specimens selected from the pith to the bark. The same phase velocity values were measured in poplar tension wood and normal wood. In...
