An accurate estimation of wood mechanical and acoustical behaviour requires simultaneous views on its structure and wave propagation phenomena. Wood structure acts as a filter. The interaction between ultrasonic waves and wood anisotropy induced by its structure is reflected by acoustic and elastic invariants and by nonlinearity in acoustoelastic response of wood under pressure.

摘要

An accurate estimation of wood mechanical and acoustical behaviour requires simultaneous views on its structure and wave propagation phenomena. Wood structure acts as a filter. The interaction between ultrasonic waves and wood anisotropy induced by its structure is reflected by acoustic and elastic invariants and by nonlinearity in acoustoelastic response of wood under pressure.
