| Sumario: | This paper reports on a study of the application of ultrasound waves in wood with the purpose of evaluating the mechanical properties of Pinus taeda. Tests were carried out to determine the properties of density at 12% moisture content (ρap,12%) and modulus of elasticity in static deflection (MOE). Ultrasound tests were also performed to find the dynamic modulus of elasticity (Ed), for purposes of comparison with the static findings. The results and analysis lead us to conclude that the nondestructive ultrasound test can be employed to obtain reliable evaluations of the mechanical properties of lumber |
