Moisture diffusion through a corrugated fiberboard under compressive loading : its deformation and stiffness response

Abstract

This research develops a model using finite element to study the response of a panel made of a typical commercial corrugated fireboard due to an induced moisture function at one side of the fiberboard. The model predicts how the moisture diffusion will permeate through the fiberboard's layers (medium and liners) providing information on moisture content at any given point throughout the structure. The short column is loaded by edgewise compression, all panel edges are simply supported. This is one type of boundary conditions; other boundary conditions can be investigated. The model predicts the deformation response, the loss of stiffness, and the swelling mechanism in all the layers of the fiberboard under the static compressive loading. The parameters studied include the moisture content at different location of the fiberboard's layers as described by the moisture diffusion law.
