Özet:

Torsion experiments are performed in order to examine the mechanical behavior of Turkish beech, pine, hornbeam, and chestnut wood specimens. Solid and tubular bars of different geometries are tested under torsional loading. The results are compared for different species and geometries of wood specimens. The shear stress-strain curves are obtained in order to show their characteristic behavior in detail. The data obtained from torsional loading experiments are used to estimate the modulus of rigidity of different wood specimens. The factors affecting the slopes of the characteristic shear stress-strain curves of different wood species under forward/backward and cyclic loading are discussed. Stress relaxation tests are performed on both pine and beech for torsional loading.
