Acoustic Velocity (AV), Eucalyptus pellita, Bending StrengthAbstract
This study was conducted to validate the bending strength of Eucalyptus pellita using the acoustic velocity method and the conventional method. Acoustic velocity was measured on slabs using Fakopp Microsecond Timer, which relies on the time-of-flight principle. Acoustic velocity was converted to the dynamic modulus of elasticity MOEdyn based on the equation MOEdyn = ρAV2. The conversion equations between MOEdyn and static MOE were established using the regression method. The bending test was conducted according to standard ISO 13061. Results show that the acoustic velocity method can be used to predict the static MOE value.
