The elastic properties of wood subjected to axial-shear combined stress conditions were examined. Wood specimens of rectangular bars of Japanese cypress were cut into those whose long axis coincided with the longitudinal direction. These specimens were loaded and twisted in and around the long axis, respectively, according to the proportional deformation loading method and the initial constant loading method. The results obtained are summarized as follows: 1) Loading methods had effects on the relationships between apparent shear moduli and conditions of combined stresses. 2) In the case of the initial constant loading method, apparent Young's moduli were influenced by conditions of tension-shear combined stresses. 3) Apparent Young's moduli under compression shear combined stresses tended to become larger than those under uni-compression, irrespectively of loading method. 4) As for the anisotropy of the apparent elantic moduli, when axial (or shear) stress was mainly applied under axial-torsion biaxial loading, the magnitude of apparent shear (or axial) modulus showed much difference between two (LT and LR) planes of the wood specimen.
