Comparative Analysis of the Nail and Screw Withdrawal Resistances of Fir (Abies Mill.), Cherry (Prunus Avium L.), Walnut (Juglans Regia L.) and Oak (Quercus L.) Wood
Öz
In this study, the nail and screw withdrawal resistance (NWR and SWR) of wooden materials obtained from Fir (Abies Mill.), Cherry (Prunus avium L.), Walnut (Juglans regia L.) and Oak (Quercus L.) on the tangential, radial and transverse cut surfaces were researched. A total of 480 each samples were prepared in conformance with ASTM 1761 in order to determine the effect of the species of wood and type of cut surface on the NWR and SWR and the NWR and SWR of these samples were measured on the universal test machine. The data obtained was analyzed statistically and the findings obtained were interpreted. According to this, the highest NWR and SWR was on the radial cut surfaces in oak. As the specific gravity increases, the NWR and SWR increases. In general, the radial cut surfaces have a higher NWR and SWR compared to the tangential and transverse cut surfaces and the tangential cut surfaces have a higher NWR and SWR compared to the transverse cut surfaces.
