Penggunaan Kaedah Dinamik Ultrasonik bagi Menentukan Pemalar Kenyal Kayu Tropika
This paper reports the determination of elastic constants for 56 tropical wood species using the dynamic ultrasonic technique. Longitudinal waves (45 kHz) were used to measure the velocity in the radial (R), tangential (T) and longitudinal (L) anisotropic directions of each sample of wood. The di...
