Resumen

SOTOMAYOR-CASTELLANOS, Javier Ramón  y  VILLASENOR-AGUILAR, José María. Ultrasound and anisotropy of Thuja plicata and Acer saccharum wood. Maderas, Cienc. tecnol. [online]. 2016, vol.18, n.3, pp.467-476. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2016005000042.

The ultrasound speed and the modulus of elasticity of the wood material follow an anisotropic behavior predicted by a theoretical model. The goal of the research was to determine the variation of the ultrasound speed and the modulus of elasticity over the longitudinal-tangential plane of Thuja plicata and Acer saccharum wood. For each species, 32 wood specimens were tested. The ultrasound speed and the modulus of elasticity were calculated in ten positions over the longitudinal-tangential plane. Experimental results were contrasted with the predictions of the proposed anisotropy model. For the T. plicata and A. saccharum woods, the ultrasound speeds were, for the longitudinal direction 5610 m/s and 5935 m/s, and for the tangential direction 1198 m/s y 1372 m/s. The moduli of elasticity were, for the longitudinal direction 11126 MPa and 24688 MPa, and for the tangential direction 530 MPa and 1320 MPa.

Palabras clave : Density; modulus of elasticity; non-destructive tests; wave speed; wood properties.
