Intra-Ring Variations in the Rolling Shear Modulus of Spruce Wood

The mechanical properties of wood are highly related to its structure, and knowledge regarding the influence of, for instance, density and fiber wall structure is needed for a better utilisation of the wood material. In this work, the Iosipescu method was used to test wood in rolling shear in order to establish the intra-ring variations in the wet shear modulus of spruce wood. The shear modulus increased from the earlywood to the latewood within the annual rings. This increase in the wet shear modulus was explained to 80% by the variations in the density of the wood.
