Abstract

Shear moduli of Calabria pine (Pinus Brutia Ten.) predicted using non-destructive test method in this study. Calabria pine logs harvested from Beşkonak, Burdur and sawn in to Radial and Tangential planks. 26 surface polyhedral NDT samples prepared in 65x65x65mm dimensions. All samples acclimatized at 20±1°C temperature and %65RH conditions. Ultrasonic shear wave velocities of Calabria pine wood calculated using time of flight (ToF) values. ToF values obtained using Olympus EPOCH 650 flaw detector and Panametrics NDT V153 shear wave transducers. Shear moduli predicted using calculated velocities. Average density and moisture content of the non-destructive test samples determined as 0.558g/cm3 and %12.66, respectively. Shear wave velocities and shear moduli of LR, LT, and RT planes were determined as 1408, 1306 and 666m/s and 1108, 952 and 248N/mm2, respectively.

Özet

Bu çalışmada Kızılçam (Pinus brutia Ten.) odunu kesme modülleri tahribatsız test yöntemi ile tahmin edilmiştir. Kızılçam tomruklar Beşkonak, Burdur yöresinden temin edilmiştir ve radyal ve teğet yönlerde kesilerek 65x65x65mm ölçülerinde 26 yüzeyli tahribatsız test örnekleri hazırlanmıştır. Test örnekleri 20±1°C sıcaklık ve %65RH’de iklimlendirilmiştir. Kızılçam odunu ultrasonik ses dalgası hızları sinyal uçuş süresi ile hesaplanmıştır. Bu süreler Olympus EPOCH 650 ultrasonik hata dedektörü ve Panametrics NDT V153 kesme dalgası transdüserleri kullanılarak elde edilmiştir. Elde edilen kesme hızları ile kesme modülleri belirlenmiştir. Tahribatsız test örneklerinin ortalama yoğunluğu ve rutubet içeriği 0,558g/cm3 ve %12,66 olarak belirlenmiştir. LR, LT ve RT düzlemlerindeki kesme hızları ve modülleri sırasıyla 1408, 1306 ve 666m/sn ve 1108, 952 ve 248N/mm2 olarak belirlenmiştir.
