In this study, mechanical properties of Oak (Quercus castaneifolia) at four different locations of Caspian forests (North of Iran) were investigated. The locations were including Asalem (37°56´55. N, 48°52´84. E), Visar (36°28´3.N, 51°32´5. E), Sangdeh (36°05´28. N, 52°25´41. E) and Golestan (36°25´41. N, 51°35´25. E). The test materials were derived from randomly chosen trees. Mechanical properties such as static bending strength, compression strength parallel to grain, impact strength and shear strength are measured on two moisture levels: green and air-dried (12% moisture content). The results obtained for the species at different geographical locations, ages, and mechanical properties. According to our findings in this research, there are positive relationships between wood density and static bending (modulus of rupture and modulus of elasticity) and the relation between wood density and other mechanical properties was not significant. Total of oak wood can be utilized in more structural application due to good density and high mechanical properties.
