摘要：

A numerical approach to evaluate the stiffness parameters for corrugated board is presented in this paper. The method is based on a detailed micromechanical representation of a region of corrugated board modelled by means of finite elements. In order to define the stiffness properties, energy equivalency is imposed between the discrete model and the equivalent plate. Exploiting a transformation matrix capable to map a constant strain/curvature vector for the equivalent plate in a displacement field of the FEM boundary nodes, it is possible to express an equivalent ABD matrix as a function of the boundary condensed stiffness matrix of the FEM model. Practical examples dealing with the computation of stiffness properties of paperboard are presented. (c) 2004 Elsevier Ltd. All rights reserved.
