Ultrasound wave propagation on some wood species growing in Chile, and its relation wih some physical properties.
In eleven forest species from Chile, the ultrasound speed propagation and its relation with some physical and mechanical properties were determined. The relation between ultrasound speed elasticity module (MOE), density, and wood structure (fiberlength, knots) were studied. The highest propagation speeds were determined with Pinus radiata and Pseudotsuga menziesii, the lowest with Fitzroya cupressoides.
