Özet

In this study, efficient of two acoustic-based non-destructive test methods were compared for determining of elastic properties on wooden structural beams. For this purpose, stress wave and longitudinal vibration non-destructive test methods and modulus of elasticity and bending strength destructive test methods were performed on 53 Black Pine (Pinus nigra var. pallasiana Arnold.) structural lumbers. Statistically compared results showed that; longitudinal vibration method was better than stress wave method for determining the modulus of elasticity. For determining the bending strength, it is suggested that. defects should be considered for better prediction (This paper was presented in IMSTEC 2016 International Material Science and Technology in Cappadocia Conference which was held on April 6-8, 2016).
