  text: 200 million m³ oil palm trunks per year are still a “waste by-product”. For
    generating added-value, material modelling and product optimization and therefore
    knowledge of the elastic properties are required. Apart from Young´s modulus parallel
    to the vascular bundles, the elastic properties of oil palm wood are not known.
    The applicability of ultrasonic testing (time of flight of three longitudinal,
    six shear and three quasi-shear wave measurements) for the characterization of
    all 12 elastic constants of oil palm wood hav-ing various densities was investigated
    under the assumption of an orthotropic material behavior. For the evaluation,
    the simplified uncorrected and the full stiffness inversion method were used.
    The lack of correlation between the density and the ultrasonic velocity when using
    flat transducers questions the applicability of this method for oil palm wood.
