A procedure for determining the nine equivalent orthotropic elastic constants for a cell-wall lamella is presented. A two-stage analytic homogenization method is proposed. It is shown to give results which are similar to those obtained from a full numerical finite element solution for an idealised representative volume element. The method, which can accommodate arbitrary proportions of cell wall constituents, is used to determine the equivalent elastic constants for lamellae in the secondary cell wall layers and the compound middle lamella of a typical softwood tracheid at a nominal 12% moisture content.
