Relationship Between Radial Compressive Modulus of Elasticity and Shear Modulus of Wood
Keywords:Anisotropic material, elasticity, shear modulus, shear test, tensor transformation, wood
AbstractWood properties in transverse compression are difficult to determine because of such factors as anatomical complexity, specimen geometry, and loading conditions. The mechanical properties of wood, considered as an anisotropic or orthotropic material, are related by certain tensor transformation rules when the reference coordinate system changes its orientation. In this paper, we used our verified shear modulus model to estimate compressive modulus of elasticity in the radial direction by means of certain established tensor transformation rules. The obtained basic engineering constants form a viable set that agrees with reliable test data and the anisotropic elasticity theory.
