DescriptionWood may be described as an orthotropic material with unique and independent mechanical properties in the directions of three mutually perpendicular axes– longitudinal ( L ), radial ( R ), and tangential (T ). These mechanical properties are also called engineering constants. Orthotropic materials are of special relevance to composite materials. Therefore, mathematical relations and experimental procedures for engineering constants of orthotropic composites can be conveniently applied to wood when considered as an engineering material. In this paper, we present how variation of shear modulus with grain slope of wood can be studied using methods of engineering mechanics of composite materials and how the results can be used to obtain some useful relations among shear modulus, moduli of elasticity, and Poisson’s ratio of wood in a two-dimensional analysis.
