A research on the determination of the relationship between density and some mechanical properties of wood

Physical, mechanical, chemical and biological properties of wood are important properties for usage area. When determining usage area, it is decided according to these properties. High mechanical properties are desirable in load bearing sections. It is desirable that the biological durability of the wood used in the external environment is high. It is well known that wood species, moisture content, wood type, place taken from the tree and wood imperfections are effective on wood properties. In this study, the relationship between mechanical properties and density of wood investigated. For this purpose, mechanical properties and density were determined on beech (Fagus orientalis L.) and poplar (Populus x euramericana I-214) woods. In the tests, the density, bending strength, modulus of elasticity, impact strength and compression strength of wood were determined. Experiments conducted according to TS 2470, TS 2474, TS 2078, TS 2077 and TS 2595 standards. The relationship between density and mechanical properties was determined using regression equations. These relationships showed by distribution graphs. According to findings; it was determined that as the density of wood increased, mechanical properties increased
