Modeling the Linear Expansion of Wood Composites

Authors

  • Otto Suchsland

Abstract

A model is presented that allows the prediction of the LE of a wood composite based on the properties of the raw material. The model disregards the effects of layer discontinuity but takes into account the inelastic behavior of wood in compression across the grain. The model predicts LE values that correspond to minimal values achieved by commercial particleboard but which are exceeded by most. This discrepancy is attributed to the effects of layer discontinuity. The LE requirement of the commercial standard for particleboard is discussed.
