Abstract
Ultrasonic waves propagation velocity and dynamic modulus of elasticity of European oak, European aspen, American cherry and wenge wood. In this work the propagation velocity of longitudinal ultrasonic waves and dynamic modulus of elasticity of selected species of hardwood of various anatomical structure and density were determined. The highest values of longitudinal ultrasonic waves velocity parallel and perpendicular to the grain and the dynamic modulus of elasticity parallel and perpendicular to the grain were noted for wenge, which is also characterised with the highest density. The properties tested perpendicular to the grain do not show such significant differences between wood species as parallel to the grain. The anisotropy of ultrasonic waves velocity is affected mostly by the type of wood structure, and thus its anatomic structure, and the anisotropy of the dynamic modulus of elasticity is affected mostly by wood density.
