Abstract

In this study the effect of different NDT methods on DYNAMIC PROPERTIES (flexural vibration of TIMOSHENKO BEAM THEORY and longitudinal vibration method) of beech wood were evaluated. Twenty nine clear samples with nominal dimension of 2×4×36 cm were selected and bending vibration in free-free beams and longitudinal vibration tests was performed on the samples. Results showed strong correlation between dynamic Young’s modulus and acoustic coefficient measured with both longitudinal vibration and flexural vibration method. The measured damping factor values were significantly higher in flexural vibration compared to longitudinal vibration method, While the acoustic converting efficiency values from flexural vibration was smaller than values of this factor in longitudinal vibration method. There was good correlation between dynamic SHEAR MODULUS of elasticity from flexural vibrations and dynamic modulus of elasticity in both methods. This finding provides possibility of estimating the SHEAR MODULUS of elasticity values based on dynamic Young’s modulus of elasticity values from longitudinal vibration test. The results also indicated the existence of good correlation between the PHASE VELOCITY in first to third modes from the bending vibration. In addition there was good correlation between sound velocity from longitudinal vibration and the PHASE VELOCITY in first to third modes from the bending vibration.
